DHT22. Connection and task
DHT22 Sensor¶
The DHT22 digital sensor can provide temperature and humidity. It is connected to a digital pin, in our case we have chosen D3 (IO25) of our board. To know more about this sensor we can see its description in the Keyestudio wiki.
Wiring¶
The DHT22 sensor is connected to a digital pin, in our case we have chosen D3 (IO25) on our board. We connect the S of the sensor to the S of pin D3 (IO25) of the board, the + of the sensor to the V of the board and the - of the sensor to the G of the board.
Task. Temperature and humidity measurement¶
It correctly connects the LED display to the DHT22 sensor and displays the temperature and humidity values every second in a legible and orderly manner.
