DHT-22 Humidity + Temperature sensor (AM2302)

DHT-22 Humidity + Temperature sensor (AM2302)
DHT-22 Humidity + Temperature sensor (AM2302) DHT-22 Humidity + Temperature sensor (AM2302)
Product Code: SB-023
Availability: In Stock
Price: ₱349



DESCRIPTION

The DHT22 (also named as AM2302) 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). Connections are simple, the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground.
 

FEATURES / SPECIFICATIONS
  • Power: 3-5V
  • Max Current: 2.5mA
  • Humidity: 0-100%, 2-5% accuracy
  • Temperature: -40 to 80°C, ±0.5°C accuracy
