Humidity Sensor System DHT11 on Arduino

Humidity Sensor is a reliable and simple electronic project for measuring the temperature and humidity in the atmosphere. The DHT11 Humidity sensor is used in the circuit and output is displayed on the LCD. It is extensively used in Heating ventilation, weather stations, Home Automation systems etc. the humidity in the atmosphere is easily detected and measured with the help of this simple electronic circuit. Let’s make our project and understand the principle.

Humidity Sensor is used for the measuring and detection of temperature in the surrounding. The DHT11 sensor is used for this detection and Arduino microprocessor sends the signals which is connected to the power supply. The potentiometer is used to control the resistive flow of current in the circuit board. So this is the basic principle and working of electronic project, let’s make our project.
