DHT11 Temperature And Humidity Sensor Module with LED

DHT11 Temperature And Humidity Sensor Module is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 sensor can be interface with any microcontroller like Arduino, Raspberry Pi, etc. and get instantaneous results. DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability.

This DHT sensor uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and outputs a digital signal on the data pin (no analog input pins needed). Its very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi.

This DHT11 module makes easy to connect the sensor to an Arduino or microcontroller as includes the pull up resistor required to use the sensor. Only three connections are required to be made to use the sensor – Vcc, Gnd and Output.

It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology. But despite its disadvantages over DHT22, it is a smaller and less expensive sensor for temperature and humidity measurement.
