Description Temperature and humidity sensor DHT22 AM2302

The DHT22 / AM2302 sensor is used to measure air temperature and humidity with increased accuracy. Data transfer is carried out over a single wire using its own protocol. It can be used in devices based on Arduino, AVR, PIC, ARM, etc. There are ready-made libraries for working with Arduino.

It differs from DHT11 sensors in greater accuracy of readings and an extended measurement range, the connection diagram and protocol are identical.

Characteristics:
Supply voltage: 3.5...5.5 V
Temperature range: -40...+80 °С
Temperature reading error: ±0.5 °С
Humidity range: 0 - 100%
Humidity error: ±2%

Reviews Temperature and humidity sensor DHT22 AM2302

Приехал на следующий день, датчик проверили и выдали новый, предварительно проверив. Все вопросы с возвратом и обменом решаются без проблем!

Датчик неисправен, постоянно показывает температуру -40
Хотелось бы замены.
