AirTube to AtomS3
-
Hello,
Im trying to connect this unit:
https://docs.m5stack.com/en/unit/tube_pressure
to AtomS3, but dont know which pin to set as the sensor pin(I have tried pin 1 and 2)I have also m5stickC, and there everything fine. this is the code example that works for me there:
#include <Arduino.h>
int sensorPin = 33; // 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/40953.6;
float P = (Vout-0.1)/3.0300.0-100.0;
Serial.printf("pressure: %f.2 Kpa\r\n", P);
delay(500);
}so if someone can tell me how to connect this pressure sensor to AtomS3, I'll be grateful.
Thanks!
