Temperature and Humidity Sensor DHT22 Module

Temperature and Humidity Sensor DHT22 Module


Do you need a small yet accurate temperature and humidity sensor? This sensor could give you a temperature reading with an accuracy of +-1°C.

It operates with a 3.5V to 5V power supply. With an operating current of 0.3mA when on use and 60µA on stand-by mode. The temperature range this sensor can detect ranges from 0°C to 50°C, and the humidity it can sense is from 20% to 90%. You could interface this to your MCU using one Digital pin, and 2 for the power supply (VCC/GND).

It has a built-in resistor for the readings to be more accurate.

You could use this with small scale temperature and humidity monitoring projects.
