How to connect DHT11 Sensor with Arduino UNO Arduino ...

20200515· The DHT11 is a basic, ultra lowcost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 ...
