Solar-Powered & Chargeable Batteries Backup

IoT Weather Station utilizes solar power to achieve operation. With built-in batteries, it can work at least a week without sunlight due to its low-power consumption capability.



IoT Weather Station


Data Storage and Retransmission

Milesight IoT Weather station can store up to 19,000 sets of historical data records safely. When the connection fails, it will continue to collect and store weather monitoring data. Once reconnected, the data collected during that period will be retransmitted to the gateway, thus avoiding data loss and ensuring data integrity.

WTS50x IoT Weather Station


Robust and Rugged

Milesight IoT Weather Station is qualified to work in harsh and wet environment with IP65 rating of its WTS Sensors and IP67 rating of its WTS Hub to protect against powerful jets of water.




LoRaWAN® Based

Milesight IoT Weather Station is compatible with industry-standard LoRaWAN® gateways.

The transmission range is up to 15 km in rural areas and 2 km in urban areas (over 30x the distance of similar weather stations).
