The WSLRW-ATH is a high-performance LoRaWAN-integrated ambient humidity and temperature sensor designed for reliable and precise environmental monitoring. It leverages a digital capacitance humidity sensor to ensure exceptional measurement accuracy and long-term stability. The sensor is available in two configurations: an integral type for standard installations and a remote type with a cable, ideal for applications requiring physical separation between the sensor probe and the wireless transmitter. Engineered with an ultra-low-power architecture and intelligent firmware, the device can operate for up to 10 years using just two AA batteries, depending on specific configuration settings. Additionally, an externally powered version is available to support deployment in high-humidity environments. The sensor transmits data over kilometer-scale distances to any LoRaWAN gateway, ensuring broad compatibility across the market. Typical application scenarios include environmental monitoring in offices, warehouses, data centers, hospitals, and agricultural facilities.
For Applications
Automatic Ventilation System, Facility Monitoring, Indoor Air Quality Monitor, Warehouse Monitoring, Temperature Monitoring
LoRaWAN communication
LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market
High Accuracy & Stable
Digital sensor with factory-calibration
10-Year battery
Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology allow the sensor can last up to 10 years with 02 x AA batteries
Optional Rain Guard and Splash Guard
For outdoor installation or place with water jets
