Advanced Sensing Technology: Equipped with a high-grade CMOS SHT30 sensor, our RS485 temperature and humidity transmitter ensures reliable and accurate measurements in environments ranging from -40℃ to 125℃ for temperature, and 5% to 95%RH for humidity. Its robust build makes it dust, rain, and snow resistant. RS485 Modbus Protocol Compatibility: This sensor features an RS485 output, supporting the widely used Modbus-RTU protocol, which enhances transmission stability over distances up to 1200 meters. It simplifies installation with its wall-mounted design and operates efficiently with a power supply ranging from DC 5 to 36V. Precision Measurement: Enjoy exceptional accuracy with temperature readings precise to ±0.3°C within the 0 to 60°C range and ±0.5°C outside this range. Humidity accuracy is maintained at ±2% within the 10 to 90%RH range and ±5% outside of it. Regular data collection is performed every 10 seconds. User-Friendly Configuration: Configuration is straightforward via DIP switches that allow address settings, aiding in easy identification and integration of multiple sensors. The system ensures high long-term stability and strong anti-interference capabilities. Practical Design and Applications: Featuring a large LCD display for real-time monitoring, this digital temperature and humidity transmitter with an IP54 waterproof rating is perfect for various uses including industrial sites, HVAC systems, agriculture, and storage areas like warehouses and greenhouses.
