RS485 Temperature and Humidity Sensor
The RS485 temperature and humidity sensor is a high-precision, industrial-grade sensor designed for demanding monitoring tasks. With its wide measuring range from -40 to 120 °C for temperature and 0 to 99.9% relative humidity, it is suitable for a variety of applications. The sensor uses high-quality digital converters and a reliable digital processing circuit to convert temperature and humidity data into RS485 signals. Its robust aluminum alloy housing makes it waterproof, heat-resistant, and durable even under extreme environmental conditions. Additionally, the breathable and dustproof probe design protects the internal components and ensures a long lifespan. Thanks to its high accuracy of ±0.3 °C at 25 °C and ±2% RH at 25 °C, the sensor provides precise and repeatable results. The sensor supports the MODBUS-RTU protocol, allowing easy integration into existing systems. With a fast sampling time of 3 seconds, it is ideal for real-time monitoring. Whether in air conditioning, building control, or industrial automationthis sensor is the perfect choice for reliable measurements.
