Product description: Tinycontrol AHT20 - temperature and humidity sensor - I2C
The AHT20 temperature and humidity sensor utilizes an I2C bus, ensuring stable and easy integration with automation systems and educational platforms. It measures temperature from -40°C to 85°C with an accuracy of 0.3°C and humidity from 0% RH to 100% RH with an accuracy of 2% . This model is fully identical to the AM2301B sensor , allowing it to be used as a direct replacement without requiring design modifications. A protective filter reduces the risk of water condensation on the surface of the measuring system , minimizing false humidity readings. Wide supply voltage range From 2.2 V to 5.5 V DC and high measurement accuracy make the sensor suitable for both hobbyist and professional applications. It works perfectly with Tinycontrol controllers . It can also be used in Arduino , Raspberry Pi , and other platforms equipped with an I2C interface.
