SONOFF AirGuard TH Lite temperature and humidity sensor Zigbee SNZB-02B SON-KIE-SNZB02B-ZB

The Sonoff AirGuard TH Lite is a compact Zigbee temperature and humidity sensor designed for indoor use. It continuously monitors the climate conditions of a room and delivers reliable, accurate readings, making it a practical addition to smart home systems.

Thanks to the Zigbee protocol, the sensor maintains a stable, energy-efficient connection with your smart home hub or central controller. The collected data can be displayed in real time in a compatible app, allowing you to track temperature and humidity remotely.

The device is especially useful for monitoring environmental conditions in living spaces, storage rooms, cellars or greenhouses. With adjustable alerts, the sensor notifies you immediately when temperature or humidity moves outside your preferred range. Its small size means it can be placed almost anywhere and easily integrated into an existing Zigbee-based smart home setup.
