Barometric pressure sensors measure fluctuations in the pressure exerted by the atmosphere. The sensors require protection from condensing humidity, precipitation, and water ingress. They are typically housed with the data logger inside an environmental enclosure. If the enclosure is airtight, the sensor's pressure port must be vented to the atmosphere.

Voltage: 3.3 - 5V
Pressure: 0 - 40KPa
It can connect a 2.5mm soft tube and detect water level and other air pressure.
Adopts the 5K ohm resistance bridge sensor.
