M5Stack Tube/Air Pressure UnitOpenELAB

Description

Tube pressure is a wide range air pressure sensor that supports -100 ~ 200Kpa. You can connect one end of the tube to the gas inlet. This sensor transmitted onto mapping value -100 ~ 200Kpa and 0.1 ~ 3.1V voltage output. Also having a protective housing for long term stability. It’s an accessory that your industrial use cannot live without.

Examples

Arduino

#include <Arduino.h>

int sensorPin = 32; // Sensor Pin

void setup() {
  Serial.begin(115200);
  pinMode(sensorPin, INPUT);  //Sets the specified pin to input mode.  设置指定引脚为输入模式
}

void loop() {
  float raw = analogRead(sensorPin);  // read the value from the sensor.  读取当前传感器的值
  float Vout = raw/4095*3.6; 
  float P = (Vout-0.1)/3.0*300.0-100.0;
  Serial.printf("pressure: %f.2 Kpa\r\n", P);
  delay(100);
