I. product overview

LoRaWAN Wireless pressure sensor with high precision and sensitivity and the ultra-low power consumption microprocessor are adopted to process the pressure signal of the medium under test into digital signal, which can display the pressure value on site and transmit the measured data wireless through the standard LoRaWAN protocol. It has the advantages of convenient installation and use, further transmission distance, stable and reliable performance and so on. It is widely used in intelligent fire protection, intelligent water supply, intelligent factory and other wireless pressure monitoring field.
