About this item

The WeAct Studio AHT30 Mini Module is a compact, high-precision digital temperature and humidity sensor ideal for embedded systems, IoT applications, and environmental monitoring. Based on the AHT30 sensor from Aosong (ASAIR), it offers excellent accuracy, long-term stability, and ultra-low power consumption in a small, breadboard-friendly package. This module uses an I²C digital interface, making it easy to integrate with popular microcontrollers such as STM32, ESP32, Raspberry Pi, and Arduino. It measures temperature with an accuracy of ±0.3°C and relative humidity with ±2% RH, making it suitable for weather stations, smart home devices, and industrial monitoring systems. The AHT30 features a fully calibrated, linearized, and temperature-compensated digital output, ensuring accurate readings right out of the box. With a fast response time and minimal power draw, it's an excellent choice for battery-powered or low-energy applications. Thanks to its wide voltage range (2.2V–5.5V) and standard I²C address, the AHT30 module offers flexible use across various platforms and development environments.
