Advanced Sensing Technology: Equipped with a high-grade CMOS SHT30 sensor, our RS485 temperature and humidity mitter 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 .<br> RS485 Modbus Protocol Compatibility: This sensor features an RS485 output, supporting the widely used Modbus-RTU protocol, which enhances mission 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.<br> 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.<br> 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.<br> Practical Design and Applications: Featuring a large LCD display for real-time monitoring, this digital temperature and humidity mitter with an IP54 waterproof rating is perfect for uses including industrial sites, HVAC systems, agriculture, and storage areas like warehouses and greenhouses.<br> Colour:Gray<br> Material:Plastic<br> Package Contents:<br> 1x RS485 Temperature Humidity Sensor<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
