DHT 11 Temperature and Humidity Sensor Module – India
A Temperature and Humidity Sensor DHT 11 is useful what your circuit is moisture or temperature specific. You can easily set your circuit on/off based on the value got from this sensor, thus a real-world reactive circuit is possible.
Here you can buy the Temperature and Humidity Sensor DHT 11 in India. Order multiple products and save per-item shipping cost in India. Local Pickup is also available in Delhi-NCR.

Buy online in India the DHT 11 – Temperature and Humidity Sensor, a low-cost digital temperature and humidity sensor module that you can use with Arduino and Raspberry pi. The benefit of using DHT 11 for your electronics project is that now you don’t need to purchase and calibrate the humidity and temperature separately, they both come embedded in a DHT 11.
It uses a capacitive humidity sensor and a thermistor to measure the moisture and temperature and emits a digital signal at fixed time intervals (say 2 seconds) on the data pin. It is quite simple to use this sensor and various example codes available around the internet. Although the sensor has 4 pins, this module is having only 3 pins, which makes it easy to work with. Two of the pins are Vcc, and ground and the third one is for reading the temperature and humidity data. Although you can possibly also take out the sensor and work accordingly.
The DHT11 measures relative humidity which is the ratio of the amount of water vapor in the air with respect to the saturation point of water vapor in the air. At the water vapor saturation point, water vapor condenses to form dew. The DHT 11 measures temperature with a surface mounted temperature sensor (thermistor) embedded inside it.
To works with the DHT11 with Arduino, you’ll need to install the DHT 11 library. In the library, all the functions required to read the humidity and temperature are already defined.
