DHT11 Temperature and Humidity Sensor Module
Non-returnable
Rs.125.00
DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. It 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).
DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, and get instantaneous results. It's very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi. DHT11 is a low-cost humidity and temperature sensor for prototyping.
