DFROBOT RS485 Temperature & Humidity Sensor

The DFROBOT RS485 Temperature & Humidity Sensor utilises a high-quality digital integrated transducer and reliable digital processing circuit to convert ambient temperature and humidity into corresponding RS485 signals. This enables reliable centralised monitoring when connected to a host computer system.

Featuring a wide measurement range, high detection accuracy, and a fast response speed, this module supports temperature detection from -40°C to 120°C and humidity detection from 0 to 99.9% RH. The sensor is fully wrapped by an aluminium alloy shell, making it both waterproof and heat resistant, which ensures suitability for harsh environments. Additionally, the probe employs a breathable and dust-proof design that effectively protects the internal circuit board and prolongs operational lifespan.
