Water proof and Explosive proof real time wireless Lora pressure transmitter (data uplink every minitue)

I. The LoRa wireless pressure/temperature sensor uses high-precision and highly sensitive pressure/temperature

sensitive components and ultra-low power microprocessors to process the pressure/temperature signal of the

tested medium into a digital signal. It can display temperature values on site and wirelessly transmit measurement

data through the LoRa protocol. It has the advantages of easy installation and use, longer transmission distance, stable

and reliable performance. Widely used in fluid temperature detection and control in industries such as smart

firefighting, smart water, smart factories, petroleum, chemical, power, hydrology, and environmental protection. The data 

transmission protocol of the LORA self-organizing network series monitoring system supports both host

mode and slave mode. External commands can be sent to the device through the LORA gateway to access the

device, read or modify relevant detection parameters; At the same time, the equipment regularly sends detection

data and other related instructions to the outside;
