DFRobot SEN0438 RS485 Temperature and Humidity Sensor is a high-precision industrial-grade RS485 temperature and humidity sensor. This sensor features a high-quality digital integrated transducer and reliable digital processing circuit to convert the temperature and humidity in the environment into corresponding RS485 signals. The SEN0438 RS485 temperature and humidity sensor can reliably perform centralized monitoring jobs with the host computer system. This sensor features a wide measurement range, high detection accuracy, and fast response speed. The module offers -40°C to 120°C temperature range detection and 0%RH to 99.9%RH humidity detection range. This sensor is waterproof and fully wrapped by the aluminum alloy shell and heat resistant makes it suitable for harsh environments.
The SEN0438 RS485 temperature and humidity sensor employ a breathable and dust-proof design that effectively protects the internal circuit board and prolongs the service validity period. This sensor features remarkable long-term stability, low latency, high resistance to chemical pollution, and superior repeatability. The SEN0438 sensor can be widely used in building automation, climatology stations in museums and hotels, climate and HVAC automatic control, and closed-loop control of HVAC systems.
