## Description

The AM2301B is an affordable enclosed temperature and humidity sensor featuring an I2C interface — a modern upgrade over the classic DHT22/AM2302 sensors that required bit-bang timing protocols. Inside is the proven AHT20 sensor, delivering reliable readings over standard I2C with support for 2.5V to 5.5V power, making it compatible with both 3.3V and 5V microcontrollers. With built-in pull-up resistors and a wired enclosed housing, this sensor is ready to connect directly to any Arduino or Raspberry Pi. Take readings as often as you like with no timing-critical protocol to worry about — just simple I2C communication. Key Features I2C Interface – Standard I2C communication, no bit-bang timing protocol needed Wide Voltage Range – 2.5V to 5.5V, compatible with 3.3V and 5V logic Built-In Pull-Ups – Ready to connect with no external resistors required Enclosed Wired Design – Protected sensor in a compact housing with lead wires AHT20 Sensor Inside – Proven, reliable temperature and humidity sensing Specifications Sensor – AHT20 Interface – I2C (single address) Supply Voltage – 2.5V to 5.5V Humidity Accuracy – ±2% RH (typical, at 20–80% RH) Temperature Accuracy – ±0.3°C (typical, at 20–60°C) Housing – Non-waterproof wired enclosed shell Ideal For IoT environmental monitoring Home automation and climate control Weather stations and data logging Arduino, Raspberry Pi, and CircuitPython projects Note: This sensor has only one I2C address, so it is not suitable for projects requiring multiple humidity sensors on the same bus.
