3x DHT22 / AM2302 Digital Temperature & Humidity Sensor for Arduino Raspberry Pi

Feature: 3 x DHT22 temperature and humidity sensor

(DHT22 - Latest, revised version from 2021 Aosong/ASAIR production)

The DHT22 temperature sensor is a high-precision sensor for measuring temperature and humidity.

In conjunction with the necessary 4.7 kOhm resistor and jumper cable, this can be connected directly to the Raspberry Pi or Arduino.

Description:

1. AM2302 Digital Temperature and Humidity Sensor is a compound temperature and humidity sensor with calibrated digital signal output. It uses digital module detection technology and temperature and humidity measurement technology to ensure high reliability and long-term stability of the product.

2. The sensor contains a capacitive humidity sensing element and an NTC temperature sensing element and is interfaced with a powerful 8-bit microcontroller. Therefore, the product has the advantages of high quality, ultra-fast response, strong anti-interference ability and high cost performance.

3. Each AM2302 sensor is calibrated in its own humidity calibration chamber. The calibration coefficients are stored in the OTP memory in the form of a program and these calibration coefficients are called up within the sensor during processing of the detection signal.

4. Single-wire serial interface makes system integration easy and fast. Ultra-small size, low power consumption and more than 20 meters signal transmission distance make it the best choice for various applications and even harsh applications.

5. Applications HVAC, dehumidifiers, test and inspection equipment, consumer products, automobiles, automatic controllers, data loggers, home appliances, humidistat controllers, medical, weather stations and other related humidity detection and control.

6. Product highlights Energy consumption, long transmission distance, automatic calibration, capacitive humidity sensor, full interchangeability, long-term stability of the standard single-bus digital output and high-precision NTC.
