Temperature and humidity sensor AM2302 (analogue DHT22)

Product description format_size zoom_out zoom_in

DHT22/AM2302 sensor is used to measure air temperature and humidity with increased accuracy. The sensor consists of a capacitive humidity sensor and a thermistor. Also, the sensor contains a simple ADC for converting analog values ​​of humidity and temperature into digital form. Data transmission is carried out over one wire using the proprietary WIRE protocol. It can be used in devices based on Arduino, AVR, PIC, ARM and other microcontrollers. To work with Arduino, there are ready-madelibraries.
 
From sensorsDHT11features greater accuracy of readings and an extended measurement range, the wiring diagram and protocol are identical.
 

Main characteristics:

  • Supply voltage: 3.5 ... 5.5 V
  • Temperature range: -40 ...+80°С
  • Temperature reading error: ±0.5°С
  • Humidity range: 0 - 100%
  • Humidity reading error: ±2%
  • Sensor polling rate no more than 0.5 Hz (no more than once every 2 seconds)
  • Dimensions 15.1mm x 25mm x 7.7mm
  • Built-in ADC
  • Data transmission over one wire
  • Analog DHT22
  • Weight: 2.4g

Contact diagram:

Pin assignment:

  • SDA - contact for data exchange between sensor and microcontroller
  • VDD - supply voltage
  • GND - common contact
  • NC - not used
