The AM2320 is a low-cost digital temperature and humidity sensor with an I2C interface — a simpler alternative to the classic DHT11/DHT22 sensors that require timing-critical bit-bang protocols. With standard I2C communication, it's easy to integrate with any Arduino, Raspberry Pi, or CircuitPython-compatible microcontroller.

This sensor is an excellent choice for maker and IoT projects where simplicity and affordability are priorities. Ready-to-use Arduino and CircuitPython libraries are available to get you up and running quickly.

Key Features

  • I2C Interface – Standard I2C communication, no bit-bang timing protocol needed
  • DHT-Style Form Factor – Familiar pinout in a compact package
  • Low Cost – Affordable option for non-critical sensing applications
  • Library Support – Ready-to-use Arduino and CircuitPython code available

Specifications

  • Interface – I2C
  • Humidity Accuracy – ±3% RH (datasheet), ~5–10% RH (practical)
  • Temperature Accuracy – ±0.5°C (datasheet), ~2–3°C (practical)
Note: This sensor is not well documented and its accuracy specifications may not be reliable. Temperature is likely accurate to within 2–3°C and humidity within 5–10%. It is not recommended for applications requiring guaranteed precision. Two I2C pull-up resistors are required and not included.

Ideal For

  • Maker and IoT projects where approximate readings are sufficient
  • Learning I2C sensor communication
  • Budget-friendly environmental monitoring
