AHT20 Introduction
The AHT20 module is a digital temperature and humidity sensor that features high precision, low power consumption, and digital output, making it suitable for a variety of applications including industry, agriculture, meteorology, home automation, and others.
AHT20 Feature
- High-Precision Measurement
Built-in 24-bit ADC, supporting synchronous acquisition of temperature and humidity with a data refresh rate of approximately 0.5Hz (default mode).
Integrated calibration function with factory pre-calibration, eliminating the need for additional calibration.
- Low-Power Design
Sleep mode current as low as 5μA, suitable for battery-powered devices (such as weather stations, sensor nodes).
- I2C Communication
Standard I2C protocol (100kHz/400kHz), default slave address is 0x38 (can be modified via hardware).
