AHT10

The AHT10 is a digital temperature and humidity sensor from ASAIR, offering high accuracy and low power consumption. It measures temperature (range: -40°C to +85°C, ±0.3°C accuracy) and relative humidity (range: 0–100% RH, ±2% accuracy).
Key features:
- I²C interface (3.3V or 5V compatible).
- Fully calibrated (no external calibration needed).
- Compact size (3×3×0.9 mm).
- Fast response and low drift.
Commonly used in HVAC systems, weather stations, and IoT devices, the AHT10 is ideal for applications requiring reliable environmental sensing. Its simple integration and low cost make it popular for hobbyists and professionals alike.
For setup, connect to a microcontroller (e.g., Arduino, ESP8266) via I²C and use libraries for quick data retrieval.

Equivalent products to the AHT10 temperature and humidity sensor include:
- SHT30 (Sensirion) – Higher accuracy, I2C interface.
- BME280 (Bosch) – Adds barometric pressure sensing.
- DHT22 (Aosong) – Digital output, lower cost.
- HTU21D (TE Connectivity) – Similar performance, I2C.
- SHTC3 (Sensirion) – Compact, low power.
These alternatives vary in accuracy, features, and interfaces but serve similar purposes.
