Description
- 1.This air pressure module uses a high-precision AD sampling chip,a 0-40KPa air pressure sensor,can be connected to a 2.5mm hose, can detect the water level and other air pressure,the voltage is 3.3V-5V,the volume is small,and the 5k resistance bridge is used on it.
2.The specific pressure value of the sensor needs to be calculated by yourself.
