Product Introduction:
This air pressure module adopts high-precision AD sampling chip, and adopts O-40KPa air pressure transmission sensor,
can be connected with a 2.5mm hose, can detect the water level and other air pressure Voltage 3.3V-5V, small size, sensor with 5k resistance bridge.

Feature:
1.Size: 18.7*13.4mm (2mm fixing hole)
2.Voltage: 3.3-5V
3.Pressure: 0-40KPa
4.This module adopts high precision AD sampling chip and 0-40KPa air pressure sensor. And it can connect 2.5mm soft tube and detect the water level and other air pressure
5.Adopt 5K ohm resistor bridge sensor, and specific air pressure value needs calculating.

Note:
the specific pressure value needs to be calculated according to the actual environment, weonly provide reading the code
that outputs the value is not the final data, we can't provide it other information.

Package includes:
4x 3.3-5V Digital Barometric Pressure Sensor Module Liquid Water Level Controller Board 0-40KPa 3.3V-5V
