How to Make a Weather Station with DHT11 Temperature ...

· The DHT11 Humidity and Temperature Sensor is made up of three main parts. A resistive type humidity sensor, an NTC thermistor (to calculate temperature), and an 8-bit microcontroller that transforms the analogue signals from both sensors into a single digital signal. VCC, Data Out, NC (Not Connected ), and GND are the four pins on the DHT11 Sensor.
