Seeed Studio (101020019) Temperature & Humidity Sensor Module

Product Overview Grove - temperature & humidity sensor pro (DHT22/AM2302) is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision make it ideal for temperature and humidity monitoring of Arduino and Raspberry Pi, you can also use it to make a thermometer and hygrometer. The DHT22 includes a capacitive humidity sensor and a high precision temperature sensor. The range of humidity sensor is 0 to 99.9 %RH with ±2% accuracy while the temperature sensor ranges from -40 to 80℃ with ±0.5℃ accuracy. With the help of a built-in 8-bit microcontroller, the DHT22 converts the analogue output of those two sensors to the digital signal, and output both temperature and humidity data via a single pin. Wide range of temperature and humidity measurement Ultra-low power consumption 20-meter signal transmission distance Factory calibrated, easy to use Dimension is 40mm x 20mm x 11mm Product Information Kit Application Type: Sensor Silicon Manufacturer: Adafruit Silicon Core Number: DHT22 Application Sub Type: Temperature Sensor & Humidity Sensor Kit Contents: Sensor Module DHT22 Product Range: -
