SONOFF AirGuard SNZB-02M temperature and humidity sensor

Improve the conditions in your environment with the SONOFF AirGuard SNZB-02M smart sensor, which monitors temperature, humidity, and air pressure. The device offers 5-in-1 measurement, including dew point and VPD calculations, providing detailed information about the current indoor climate. Zigbee 3.0 communication allows you to integrate the sensor into your smart home system and create automated scenarios that respond to changes in environmental conditions.

Comprehensive monitoring of environmental conditions

The SONOFF AirGuard SNZB-02M allows you to monitor key environmental parameters in real time. The sensor measures temperature, humidity, and atmospheric pressure, and additionally calculates dew point and VPD values, providing a more complete picture of indoor conditions. Monitoring air pressure also allows you to observe changes that may indicate shifts in weather conditions.

Precise measurements and fast alerts

High measurement accuracy allows you to detect even slight changes in the environment. The sensor measures temperature with an accuracy of ±0.2°C, humidity with an accuracy of ±2% RH, and pressure with an accuracy of ±0.1 hPa. Users can set their preferred temperature, humidity, and pressure ranges and receive immediate notifications in the app when these limits are exceeded, allowing them to respond quickly to changing conditions.

Zigbee smart automation

Support for the Zigbee 3.0 standard allows the sensor to connect to other smart home devices via a Zigbee hub. Based on current readings, you can create automated scenarios, such as turning on a fan, humidifier, air conditioner, or window opener when specific conditions are detected. This solution allows you to automatically adjust the environment to your current needs.

Stable communication and long battery life

Zigbee 3.0 wireless communication ensures stable operation with compatible devices and allows for flexible placement of the sensor in any desired location. Powered by a single CR2477 battery, it provides over 2 years of operation, so the device does not require frequent battery replacement. The lack of wires allows for installation in various locations, such as shelves, corners, near windows, or on ceilings.

Wide range of applications in various rooms

The SONOFF AirGuard SNZB-02M is ideal for any setting where monitoring indoor environmental conditions is important. It can be used in the living room, a child’s room, the bathroom, or a greenhouse to help maintain appropriate temperature and humidity levels. Thanks to its automation features, it can also support the management of devices responsible for ventilation, heating, or humidity control.

Compact design and easy installation

The small housing, measuring 45 × 45 × 17.6 mm, allows the sensor to be placed in many locations without taking up much space. The device weighs 27.3 g including the battery and is made of PC plastic. The kit includes installation accessories, such as a metal plate, 3M double-sided tape, and a mounting screw, allowing you to adapt the installation method to the chosen location.
