Monitor temperature and humidity in different rooms. The Sonoff sensor provides accurate data that it refreshes every 5 seconds. It also allows you to remotely monitor the temperature in real time and sends a notification in the application when the set temperature value is exceeded. It also stores data in the cloud, so you get convenient access to your measurements.

Various applications
The Sonoff sensor will work well in rooms whose area does not exceed 120 meters. The product can be used in places such as terrariums, wine cellars, music rooms, incubators, greenhouses, etc. You can also use it at home, for example a children's room.

High accuracy
The device is equipped with a Swiss hygrostat that measures temperature and humidity with an accuracy of ±0.2°C/RH. In addition, the measured values are updated every 5 seconds, so you can always have up-to-date information. You can also set the temperature unit to °C or °F.

Convenient control
The sensor is controlled from the application. In this way, you can easily read the warning, for example, when the temperature is exceeded. What's more, you can add the device to Home Assistant via eWeLink or use it with other smart home devices - when the humidity drops below 40%, the humidifier will automatically turn on. Sonoff SNZB-02D also supports Amazon Alexa and Google Home, so you can check the temperature or humidity in the room with a simple voice command.
