Wemos D1 Mini and DHT11 Shield Humidity & Temperature

DHT11 Shield Humidity & Temperature (single pin - retired)

From the Wemos DHT11 shield specs the DATA OUT pin is connected to D4 of the Wemos.

Note: this is ONLY for v1.0.0 of the DHT11 shield, since v2.0.0 uses I2C and pinned differently.

Tasmota Configuration

In the Configuration -> Configure Module page, select the following:

  • D4 GPIO2 : 01 DHT11

Tasmota Main

After reboot of the device the temperature and humidity are displayed.

Note: Having the shield compact on top of the processor increases the temperature. In normal Mode this can be up to 6°C. So you should add sleep mode. Adding normal "Sleep 100" and putting the sensor vertically reduces the temperature difference to 2°C
