What Is Water Sensor PCB?
Water sensor for rain gauge
A water sensor PCB is a circuit board you employ in sensor devices to determine the water level across different functions.
You can have different configurations of water sensor PCBs to make float sensors, ultrasonic sensors and water pressure sensors.
You use water sensor PCBs in detecting water presence especially where you are not to have water such as a leakage.
Furthermore, you can furnish a water sensor PCB to automatically shut down water supply when it detects a leakage for instance.
Which Are The Main Components Of Water Sensor PCB Assembly?
You find the following main components in the assembly of a water sensor PCB assembly:
Water sensor PCB circuit
You find water sensor PCBs composed mainly of transistors which switches current to electrical probes.
The probes provide an electrical communication path between the transistors and LEDs.
Light emitting diodes in a water sensor PCB carry out the function of indicators.
Where you have rising water levels, the transistors switch current to LEDs via electrical probes causing them to glow.
Electrical resistors provide restriction to electric current flow in accordance with the rating of the water sensor PCB.
You can have multiple resistors in different connections with your water sensor PCB to achieve a desired overall resistance level.
A transformer is preferable rather than a rectifier due to the need of using AC power supply of a pure form.
You can employ a transformer with a power output in the milliampere range from a voltage source.
What Is The Working Temperature And Humidity Of Water Sensor PCB?
The working temperature and humidity of a water sensor PCB influences its functionality and performance.
Different factors such as geographical location and climate patterns influence the temperature and relative humidity of an area.
Relative humidity refers to the quantity of water vapor in the air.
Controlling the temperature and relative humidity of a water senor PCB is fundamental in ensuring good performance.
Having high humidity levels can affect the attachment of components on a water sensor PCB leading to detachments.
Contrarily, very low humidity can result in the quick evaporation of flux resulting in an insufficient attachment of board components.
Having excess temperature melts the solder paste weakening components attached to the water sensor PCB.
On the other hand, low temperature can result in poor adhering of the components due to highly viscous solder paste.
You find the working humidity of a water sensor PCB provided as a range rather than absolute value.
You consider an operating range of between 35 % and 65 % relative humidity as ideal for a water sensor PCB.
Furthermore, you can operate your water sensor PCB comfortable within a temperature range of 68 to 78 oF.
Attaining these operating ranges where not naturally possible requires implementation of certain control measures such as air conditioning.

The two distinct parts consist of different materials with the associated property of conduction and insulation respectively.
You find the material you employ on the water sensor PCB determines its thermal, electrical and mechanical characteristics.
The following materials are common on a water sensor PCB:
The conductive part of the water sensor PCB encompasses copper material which has good electrical transfer properties and reduced resistance.
Additionally, you find copper widely available making it a low cost alternative to other superior metals such as silver and gold.
You have many water sensor PCBs furnished on a rigid board consisting of substrate material of a rigid nature.
Ceramic material such as aluminium nitride finds common use for such rigid boards for various reasons.
Using ceramic material offers your board impressive insulation quality due to its high thermal conductivity.
Furthermore, ceramic material can sustain high temperatures of operation while providing high resistance to water absorption.
You also find FR-4 material employed for water sensor PCBs consisting of a combination of glass fibre and epoxy resin.
When compared to ceramic material, FR-4 offers you a cheaper and affordable option with increased versatility.
Alongside good electrical insulation, you find FR-4 has impressive dielectric qualities with high strength-to-weight ratio.
Additionally, you find using it in water sensor PCB possible due to its favorable resistance to moisture.
What Are The Types Of Water Sensors Used In Water Sensor PCB?
Water sensors allow you to determine the level of water in different containments such as storage tanks.
You can also employ these sensors to determine leakages of water from their enclosures.
There are different configurations of water levels sensors employing different technologies in the circuit board construction.
Consequently, we have different available types of water sensors as follows:
Rain water sensor PCB
Sensores de Nível Óptico
The operation of an optical level sensor is simple consisting of a phototransistor and a light emitting diode.
Exposure of the sensor tip to the atmosphere when in water causes a low energy infrared refraction to a detector.
You find the optical level sensor favorable when employed for many sensing applications that are point level with reliability requirements.
You can use this sensor type for various detection levels in storage vessels of any size.
Where you are likely to experience leakages, optical level sensors are useful in detecting saving considerable costs in losses.
These sensors can detect very small liquid quantities with the capability to withstand high temperatures and pressure.
Additionally, you find these sensors are compact and consist solid state components thus lack movable parts.
However, the sensor requires power and having to place the sensor in the water or liquid can be contaminating.
Float Switch Sensor
A float switch sensor consists of a magnet and switch of a magnetic reed fashioned in a floating device.
As the liquid media changes in level, so does the float causing a corresponding opening or closing of the switch.
You note that the float switch sensor as a simplified design that is cost effective and reliable. You can mount the float switch sensor either vertically or horizontally depending on your storage tank’s design and construction.
Floating switch sensors have no power needs finding direct use for different liquid media such as water and chemicals.
Nonetheless, these sensor type consist moving parts and requires direct contact with the media.
Conductive/Resistive Level Sensors
You use these sensors for industrial applications in measuring liquid levels of conductive media.
Such media includes water in boilers, reagents and very corrosive substances.
The sensors employ probes to decipher the media conductivity consisting an electrode pair accepting AC input.
One of the probes is long and the other short with the former outputting low voltage.
You have the switch on the shorter probe that activates when current flows though the probes immersed in the liquid media.
The current flow signifies the level of fluid media and provides a safe measure due to the low values.
Conductive levels sensors are cost effective solid state devices lacking movable parts and simple to use.
However, you only use them for conductive fluids while needing direct contact with the measured media making them liable to corrosion.
Capacitance Level Sensors
With this sensor type, you find a probe useful in the determination of the water level.
The changes in the water level deciphered into signals of analog property finding use in water treatment and food plants.
The probes in capacitance level sensors consist of wires insulated by polytetrafluoroethylene.
However, you can find probes furnished from stainless steel which provides better responsiveness when taking measurements.
Using a capacitance level sensor is simple and non-invasive and their solid state composition means a lack of moving parts.
Nonetheless, you have limited use of these sensors in terms of compatible liquid types while also requiring calibration.
Vibrating (Tuning Fork) Sensor
You suitably employ the vibrating sensor in detection of overfills or where running out of fluid media is undesirable.
The vibrating sensor employs a sensing element in the shape of a fork hence the name tuning fork.
The tuning fork energizes by piezoelectric means causing mechanical vibration at a frequency of about 1200 hertz.
You find this frequency changes when you bring the fork in contact with a liquid or fluid.
An oscillator picks the change in frequency after which it converts it into a digital signal for output.
While the vibrating sensor is invasive, it is a cost effective solution that is simple to use and maintain.
You can employ the tuning fork sensor to detect leaks and excess filling for a wide range of substances.
Industries such as mining, beverage and chemical processing employ vibrating sensors for level control.
Sensores de Nível Ultrassônico
You use ultrasonic level sensors in the determination of a materials’ bulkiness and liquid levels especially those of a sticky nature.
This sensor type determines the liquid levels by reflecting audio waves on the liquid surface.
The sensors then determine the level by decoding the strength of the signal and the duration of travel.
A transducer is handy when deciphering, however, response is subject to different atmospheric elements such as pressure, temperature, humidity and turbulence.
Ultrasonic level sensors consist of solid state material and their indifference to the properties of measured liquid make them highly reliable.
Nevertheless, these sensors are expensive and subject to certain environmental elements such as temperature, pressure and moisture.
While there is some similarity of these sensors with the ultrasonic level sensors, they differ in certain aspects. With this sensor, you find the reflected waveforms travel at light speed but subject to the fluid’s dielectric properties.
The microwaves are sent to the radar via an antenna before reflection back. You note the duration of signal transmission is proportional to the fluid level.
Using a microwave/radar sensor ca afford you increased accuracy of level data since it is impervious to environmental elements.
Furthermore, using this sensor type is suitable for a wide range of substances including water and with no need for calibration.
Additionally, the sensor does not have to be in contact with the measured fluid. Consequently, you can employ the microwave/radar sensor in determining water levels in treatment plants.
However, you find these sensors have premium prices while they allow you only a certain range of performance.
Use of the microwave/radar sensors is common where you have liquid media in the presence of many environment elements.
