General Description
The SenSource wireless differential pressure sensor
measures the pressure difference between two input
ports and transmits the measurement to cloudbased
system.
• Measurement range: -500 Pa to 500 Pa
• Calibrated and temperature compensated

Principle of Operation
The differential pressure sensor measures the pressure
difference between two ports. When viewing the
sensor from the top, the right inlet port is the positive
or high side pressure input. When the pressure on this
port is greater than the left port the sensor produces
a negative pressure reading. When the pressure is
greater on the left port the sensor produces a positive
pressure reading.

Example Applications
• Building/Room Pressure
