Wireless Room Differential Pressure Sensor


Wireless Room Differential Pressure Sensor utilizes the advanced Piezo technology from Germany allows high accuracy, stable and ultra-low power consumption.

Reliable & Secured Wireless Connection

  • Sub-Ghz technology from Texas Instruments allows reliable wireless connection and secured data by AES-128

10-year with a single battery

  • Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology fromTexas Instruments allow the sensor can last up to 10 years with a single battery AA.

High accuracy

  • 3% of reading, drift is only 0.05 Pa/year

Environment Protection
