Digital Pressure 0- 40KPa

Voltage: 3.3 -5V

Pressure: 0 -40KPa

The module uses a high-precision AD sampling chip and a 0-40KPa Air pressure sensor. It can be connected to a 2.5mm tube and detects water level and other pressure. 

5K Ohm resistance bridge sensor, the specific pressure value needs to be calculated.
