JUN-ELECTRON Temperature and Humidity Digital Sensor Electronic Module for Arduino

* DHT22 is a low-cost humidity and temperature measuring sensor. It consists of thermister for temperature measurement and capacitive humidity sensor humidity measurement. The feature which gives importance then another sensor is that you can get data after two seconds. * It is very easy to use, just connect the first pin from left with supply then get data from the second pin. Its last pin used for ground. * It has higher accuracy and precision, this feature it can replace expensive imported SHT10 temperature and humidity sensor. This sensor is used to measure environment temperature and humidity to meet the high demand. * This sensor has reliability and good stability. It is easy to combine with a special sensor control expansion board, which is easy to use for temperature and humidity perception. * DHT22 is digital humidity sensor, designed for analog sensor interfacing. It consists of 4.7 K to 10 K resistor, which can be used as pull up from data pin to Vcc. It has four pins
