The DHT22 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
AM2302 digital temperature and humidity sensor is a calibrated digital signal
output temperature and humidity composite sensor. It uses a dedicated digital
module acquisition technology and temperature and humidity sensing technology
to ensure that products with high reliability and excellent long-term stability

Application range：
HVAC, dehumidifiers, testing and testing equipment, consumer products, automotive, automatic control, data loggers, home appliances, humidity regulators, medical, weather stations, and other related humidity detection control.

Package Included:
2 x DHT22 temperature and humidity sensor
