Tinycontrol Temperature and Humidity Sensor AHT20 (AM2301B) for LAN Controller LK3 and LK4

Reliable monitoring of temperature and humidity is crucial for the proper functioning of many applications – from smart homes to industrial deployments. With high measurement accuracy of ± 0.3 °C and humidity accuracy of ± 2 % RH, you will always receive trustworthy data. The digital I2C interface ensures stable and error-free information transmission, which is particularly appreciated during long-term monitoring. The wide measurement range from -40 to +85 °C allows use in demanding conditions and outdoor environments.

Designed for reliability and easy integration

A unique advantage is the special protection against condensation, which eliminates erroneous humidity readings and ensures accuracy even in high-humidity environments. The flexible power supply of 2.2–5.5 V allows easy incorporation into various projects, including systems with Arduino or Raspberry Pi. The compact design along with a practical RJ-12 cable significantly simplifies the installation and replacement of the sensor, making it quick to deploy exactly where needed.
