Arduino Uno Temperature and Humidity

The DHT11 is a digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends out a digital signal on the data pin (no analog input pins needed). Its simple to use, and the update timing of the sensor is about 2 seconds. Thermistor temperature circuits can be much quicker and are very accurate in measuring temperature. We will be using the DHT11 sensor to measure temperature and humidity. A separate thermistor circuit will also be used to measure temperature on an analog input. This will be all done on our Arduino UNO R3 controller on our super starter kit. Let’s get started. This kit is available from Amazon.
