SONOFF AirGuard TH temperature humidity air pressure sensor Zigbee SNZB-02M SON-KIE-SNZB02M

The SONOFF AirGuard TH SNZB-02M is a Zigbee sensor that measures temperature, humidity and air pressure at the same time. Its compact white design makes it a practical choice for smart home setups that depend on accurate environmental data.

The Zigbee connection allows the sensor to communicate quickly and reliably with other compatible devices and hubs. This makes it possible to build automated routines, such as controlling ventilation or heating based on the measured readings.

The built-in pressure sensor is especially useful for weather observation and tracking atmospheric changes, while humidity monitoring helps maintain a comfortable indoor climate. The model designation SNZB-02M makes it straightforward to add the sensor to existing Zigbee-based smart home systems, extending their sensing capabilities.
