Brand: Generic
Category: Water TDS, pH, Flow, Level and Pressure Sensor

If you are working on a device that converts an input mechanical pressure into an electrical output signal. Then this Sensor is essential for you. These types of sensors are used in altimeters, barometers, sensing printer ink levels, the airflow rate in equipment, IT center/ computer cooling systems, semiconductor process equipment, and laser measurement.

You can Purchase this Sensor from Robu.in at a reasonable price.

This Pressure Transducer is Part of All New Product  Line Up from Robu. in. The Pressure Transducer is made from High-Quality stainless steel material providing it with rigidity. The transducer comes with a standard thread size of G1/4 inches and can work in both air and water. The sensor gives a digital output in the range of 0.5V to 4.5V while operating at 5VDC. The sensor has stable performance characteristics with a long operation life.

  1. Pressure Detection in Oil Tank, Gas Tank.

The interface of  Pressure Transducer With Arduino:

Generic Connection

Source Code for Pressure Transducer Sensor:

Water pressure sensor demo(Computer serial port)
- Obtain the water pressure through the output voltage
of the sensor.

Water Sensor Key Parameter
- Parts No.:KY-3-5
- Sensing range: 0 - 1.6 MPa
- Input Voltage: 5VDC
- Output Voltage: 0.5 - 4.5 VDC
(Linearly corresponding to 0 - 1.6 MPa)
- Accuary: 0.5% - 1% FS

Water Sensor Calibration

The output voltage offset of the sensor is 0.5V (norminal).
However, due to the zero-drifting of the internal circuit, the
no-load output voltage is not exactly 0.5V. Calibration needs to
be carried out as follow.

Calibration: connect the 3 pin wire to the Arduio UNO (VCC, GND and Signal)
without connecting the sensor to the water pipe and run the program
for once. Mark down the LOWEST voltage value through the serial
monitor and revise the "OffSet" value to complete the calibration.

After the calibration the sensor is ready for measuring!

const float OffSet = 0.483 ;

float V, P;

void setup()
Serial.begin(9600); // open serial port, set the baud rate to 9600 bps
Serial.println("/** Water pressure sensor demo **/");
void loop()
//Connect sensor to Analog 0
V = analogRead(0) * 5.00 / 1024; //Sensor output voltage
P = (V - OffSet) * 400; //Calculate water pressure

Serial.print(V, 3);

Serial.print(" Pressure:");
Serial.print(P, 1);
Serial.println(" KPa");
