DHT22 Temperature and Humidity Sensor
$14.04The DHT22 Temperature and Humidity Sensor is a highly accurate and reliable digital sensor for measuring temperature and humidity in various applications. It is an upgrade from the DHT11 sensor, offering improved accuracy and range, and is widely used in a variety of applications such as home automation, weather monitoring, and industrial control. The DHT22 uses a capacitive humidity sensing element and a thermistor to measure the relative humidity and temperature, respectively. The sensor provides a digital output via a single wire interface, making it easy to connect to a microcontroller or other digital circuit.

DHT22 Temperature and Humidity Sensor Module
$17.28DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.
