Temperature and humidity sensor AHT20 (same as AM2301B)
Temperature and humidity sensor AHT20 (same as AM2301B)
Temperature and humidity sensor with a cable terminated with an RJ12 connector (I2C bus). The sensor features with a special filter on the chip's surface that reduces the risk of water condensation (which typically results in a constant reading of 100%).
Recommended for our LK3.9, LK3.5+, LK4, LK4mini controllers and tcPDU strip, as well as for Arduino, Raspberry Pi and other projects.
This sensor operates on the same settings as the AM2301B and can be used interchangeably in all projects.
