High-precision digital temperature and humidity sensor with I2C interface and condensation protection.
This high-quality AHT20 sensor offers reliable temperature and humidity measurement via the digital I2C bus. Thanks to a special filter on the chip surface, it effectively eliminates the issue of water condensation, which in standard sensors appears as a constant 100% humidity reading. The sensor is fully compatible with LK3.5, K3.9, LK4 controllers and can also be used in projects with Arduino, Raspberry Pi, and many others.
The AHT20 is functionally identical to the AM2301B sensor and can be used interchangeably in projects. Connection is provided by a standard RJ-12 connector at the end of a 27 cm cable, making installation and replacement easy.
Universal compatibility
The AHT20 sensor is fully compatible with LK3.5, K3.9, and LK4 controllers from Tinycontrol. Thanks to its standard I2C interface, it can also be easily integrated into projects based on Arduino, Raspberry Pi, and many other platforms.
Condensation protection
A common problem with humidity sensors is false readings of 100% humidity when condensation forms on the chip surface. The AHT20 solves this issue using a special filter that significantly reduces condensation risk, ensuring more accurate measurements even in demanding conditions.
Easy installation
Thanks to its approximately 27 cm long cable terminated with a standard RJ-12 connector, installing the sensor is very simple. Its compact dimensions allow placement even in tight spaces, expanding its usability in various applications.
