DHT11 Digital Relative Humidity and Temperature Sensor Module

For an accurate reading of the relative humidity and ambient temperature, this DHT11 Digital Relative Humidity and Temperature Sensor Module is pre-calibrated using resistive sensing technology in conjunction with an NTC thermistor. Aosong’s highly well-liked and reasonably priced DHT 11 break-out board makes it simple to install the DHT11 sensor module.

Additionally, the board has an 8-Bit microcontroller with great performance that is linked to the DHT11 sensor module. One data pin on the DHT11 receives a digital signal as its output. Every two seconds, or 0.5 Hz, the sensing update frequency must be measured.

The gadget is the perfect sensor setup to be immediately connected to any type of microcontroller board, such as an Arduino, thanks to its entire configuration. The board has an inbuilt LED, a pull-up resistor across the data line and Vcc, and a bypass capacitor between Vcc and Gnd as added features.

A straightforward, incredibly affordable digital temperature and humidity sensor is the DHT-11. It measures the ambient air using a thermistor and a capacitive humidity sensor before emitting a digital signal on the data pin (no analogue input pins are required).

Although it’s quite easy to use, time is crucial in order to capture data. The one significant drawback of this sensor is that it only provides fresh data once every two seconds. For this reason, please set the sensor reading interval in your code to at least two seconds. This sensor operates in a narrower temperature/humidity range and is less accurate and precise than the DHT22.
It is a smaller and less expensive sensor for measuring temperature and humidity, nonetheless, in spite of its shortcomings over the DHT22.

Applications : It includes HVAC, automobiles, dataloggers, testing and inspection tools, consumer products, automatic controls, weather stations, home appliances, dehumidifiers, medical devices, and more.
