THW1791Low power wireless pressure temperaturesensor

Overview

THW1791Low power wireless pressure and temperature sensor, collecting one channel of pressure and one channel of temperature.After being collected and logically processed by the microcontrollerpassLPWANWireless communication transmits data to wireless receiving terminals for centralized monitoring. The wireless temperature sensor is powered by a large capacity lithium-ion battery and designed with low power consumption.

The pressure transmitter adopts digital, low-power, high-precision, and high-sensitivity pressure sensitive components. Through a stable, reliable, and anti-interference amplification circuit, the pressure signal of the measured medium is converted into a standard digital signal,Implement pressure collection and processing. Optional with multi-stage heat sinks, suitable for high-temperature applications. The temperature sensor canselectNTCorPT100Sensors.
