Description
Description
This module adopts high precision AD sampling chip and 0-40KPa air pressure sensor.
It can connect 2.5mm soft tube and detect the water level and other air pressure.
This module is used to measure the ambient pressure and the pressure difference of liquid levels.
Specification:
Voltage: 3.3-5V
Pressure: 0-40KPa
Dimensions: 18x13mm/0.71×0.51inch(2mm fixing hole)
Color: Red
This sensor has 4 pins:

#include <Q2HX711.h>
#include <Average.h>
const byte MPS_OUT_pin = 2; // OUT data pin
const byte MPS_SCK_pin = 3; // clock data pin
int avg_size = 10; // #pts to average over
Q2HX711 MPS20N0040D(MPS_OUT_pin, MPS_SCK_pin); // start comm with the HX710B
Average<long> ave(avg_size);
void setup() {
Serial.begin(9600); // start the serial port
}
void loop() {
ave.push(MPS20N0040D.read());
Serial.println(ave.mean());
}
After running the code, you will see the following image in the serial monitor.
- VIN: Module power supply – 3.3-5 V
- GND: Ground
- SLC: I2C Clock
- OUT: Digital output data
