DHT11 temperature and humidity sensor is a popular and cheap sensor that can be used in a fairly wide range of temperatures and relative humidity. Let's take a look at how to connect it to the Arduino and how to read data from it.
To create a home weather station or thermometer, you need to learn how to match the Arduino board and devices for measuring temperature and humidity. Temperature measurement can be managed with a thermistor or a DS18B20 digital sensor, but more sophisticated devices are used to measure humidity — the DHT11 or DHT22 sensors. In this article, we will explain how to measure temperature and humidity with the help of Arduino and these sensors.
