DHT22 & DHT11 Devices

IoT One Cloud has support for DHT11 and DHT22 devices to be used to sample both Humidity and Temperature. Note that these devices require the DHTXX and PIGPIOD programs to be installed and running. Visit this section for details on how to setup.

Now connect the DHT22 as shown

DHT22 Wiring diagram

Note that there is a 10k resistor between power and data lines, this is to add some current to the data line in order for it to be delivered. It may not work properly otherwise.

Before adding the device to the hub with your client, you may wish to ensure correct connections and data. To do this, visit DHTXX Device Testing.
