Description Advanced Sensor Technology: Equipped with a high-quality CMOS SHT30 sensor, our RS485 temperature and humidity meter ensures reliable and accurate measurements in environments ranging from -40 to 125 for temperature and 5% to 95% RH for humidity. Its rugged construction makes it resistant to dust, rain and snow. RS485 Modbus Protocol Compatibility: This sensor features an RS485 output that supports the widely used Modbus-RTU protocol, improving mission stability over distances up to 1200 meters. It simplifies installation with its wall-mounted design and works efficiently with a power supply from DC 5 to 36V. Precision Measurement: Enjoy exceptional accuracy with temperature readings accurate to 0.3C within the range of 0 to 60C and 0.5C outside this range. Humidity accuracy is maintained at 2% within the range of 10 to 90% RH and 5% outside it. Regular data collection is performed every 10 seconds. User-friendly configuration: Configuration is simple via DIP switches that allow address settings, facilitating easy identification and integration of multiple sensors. The system ensures high long-term stability and strong anti-interference capabilities. Practical design and applications: With a large LCD screen for real-time monitoring, this digital temperature and humidity meter with an IP54 waterproof rating is perfect for various applications, including industrial areas, HVAC systems, agriculture, and storage areas such as warehouses and greenhouses.
