The DHT22 is a basic, low-cost digital temperature and humidity sensorIt 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 dataAM2302 digital temperature and humidity sensor is a calibrated digital signaloutput temperature and humidity composite sensor. It uses a dedicated digitalmodule acquisition technology and temperature and humidity sensing technologyto 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:

1/5pcs DHT22 temperature and humidity sensor
