DFRobot Gravity DHT22 Temperature & Humidity Sensor

The compound that has been calibrated digital signal output of the temperature and humidity sensors is found in the DHT22 capacitive humidity sensing digital temperature and humidity module. To guarantee that the product has great long-term stability and high dependability, temperature and humidity sensor technologies as well as specialized digital module collection technology are applied.

The sensor is coupled to a high-performance 8-bit microprocessor and consists of wet capacitive sensor components and high-precision temperature measurement sensors. The product is reasonably priced, of high quality, responsive, and has a robust anti-jamming feature. Standard single-bus interface for rapid and simple system integration. It is the finest option for all applications, even the most demanding ones, because to its small size, low power consumption, and signal transmission distance of up to 20 meters.

With its increased precision, the DHT22 temperature and humidity sensor can take the place of the costly SHT10 imported model. In order to meet the increased demand, it can measure the humidity and temperature of the surroundings. The product has high reliability and good stability. If it’s used and combined with a special sensor Arduino expansion board, it will be easily implemented the interactive effect related to the temperature and humidity perception. DHT22 digital temperature and humidity sensors are designed for analog sensor interfaces. The analog port will be used as the digital which will not occupy the original digital port of the Arduino. The lines of the sensor can transform the analog function to digital that can be used on the digital port.
