Description
The simplest way to add temperature and humidity to a project. The DHT11 sends both readings over a single data wire, and ready-made libraries exist for every popular board.
Features
- Humidity 20–90 % RH, ±5 % RH
- Temperature 0–50 °C, ±2 °C
- Single-wire digital output – no ADC needed
- 3.3–5.5 V supply; the module has the 10 kΩ pull-up already fitted
- 3 pins: VCC, DATA, GND
Good to know
Read the sensor no more than once every 1–2 seconds. For more range and accuracy (−40 to 80 °C, 0–100 % RH) choose the DHT22.
