SONOFF AirGuard SNZB-02M Temperature and Humidity Sensor
Description
About this product
The SONOFF AirGuard SNZB-02M temperature and humidity sensor monitors temperature, humidity, and air pressure. The device offers 5-in-1 measurement, including dew point and VPD, providing detailed information about the indoor climate. Zigbee 3.0 communication enables integration with smart home systems and the creation of automated scenarios.
5-in-1 Measurement
The SONOFF AirGuard SNZB-02M monitors temperature, humidity, air pressure, and calculates dew point and VPD. This gives the user a fuller picture of the conditions in the room, allowing for better management of the indoor climate.
Accurate Measurements
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. This allows for the detection of even slight changes in the environment and quick responses to changing conditions.
Zigbee 3.0 Integration
Support for the Zigbee 3.0 standard allows the sensor to connect with other smart home devices via a Zigbee hub. This enables the creation of automated scenarios that respond to changes in environmental conditions and adjust the environment to the user's needs.
Long Battery Life
Powered by a single CR2477 battery, the device provides over 2 years of operation. The lack of wires allows for flexible installation in various locations, such as shelves, corners, or near windows, without the need for frequent battery replacements.
Compact Design and Installation
The housing dimensions of 45 × 45 × 17.6 mm and a weight of 27.3 g allow the sensor to be placed in many locations without taking up much space. The package includes a metal plate, double-sided 3M tape, and a mounting screw, allowing for installation to be tailored to the chosen location.
