Product description: Digital temperature and humidity sensor DHT22 - DFRobot SEN0137
DFrobot's DHT22 digital humidity and temperature sensor module provides precise measurementsand hasa short response time combined with high reliability and resistance to interference. The sensor is very small, and its implementation into the system is easy and fast, making it a very good choice for any project using temperatureand humiditysensors.
