Features:
Adopt LoRaWAN standard protocol
LoRa spread spectrum modulation technology has extremely high sensitivity
Equipped with an external antenna, the communication distance can reach 1KM ~ 10KM (depending on the interference of the surrounding environment)
The sensor has a wide measuring range and high stability
Range: 0~2, 5, 10, 20, 50m, etc. H2O (optional), accuracy ±0.5%FS, ±0.2%FS/year
Low power consumption design, built-in 19000mAh high-capacity battery
IP65 protection level, can be used in harsh indoor and outdoor environments
The measured pressure is too high/low to automatically upload alarm data
Battery low voltage automatic upload alarm
