Digital 2-in-1 Ambient Humidity & Temperature Sensor


The DHT-11 sensor is a popular and inexpensive sensor that is often used to monitor the indoor climate, e.g. in the bathroom or basement. The sensor is often sold on small adapter boards that simplify its use. If you want to use the sensor alone (i.e. without adapter board, with 4 connection wires), you need an additional 5kΩ pull-up resistor.

With the sensor you can easily monitor the indoor climate with the help of our Sensate Monitor App. Through the clever use of notification rules, you can also be notified e.g. if there is a risk of mould. If you need other forms of interaction besides the integrated push notifications, you can easily integrate the sensor into your smart home hub via MQTT or connect it to other products via IFTTTT.
