Advanced Sensing Technology: Equipped with a high-grade CMOS SHT30 sensor, this RS485 temperature and humidity sensor ensures reliable and accurate measurements in environments ranging from -40°C to 125°C for temperature, and 5% to 95%RH for humidity. Its robust construction provides resistance to dust, rain, and snow. RS485 Modbus Protocol Compatibility: The sensor features an RS485 output supporting the widely used Modbus-RTU protocol, enabling stable communication over distances up to 1200 meters. It offers easy installation with a wall-mounted design and operates efficiently with a DC power supply between 5V and 36V. Precision Measurement: Delivers high 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 ±2% within the 10 to 90%RH range and ±5% outside of it. Data is collected every 10 seconds. User-Friendly Configuration: Simple configuration via DIP switches allows for address setting, facilitating easy identification and integration of multiple sensors. Designed for high long-term stability and strong anti-interference performance. Practical Design and Applications: Includes a large LCD display for real-time monitoring. With an IP54 waterproof rating, this digital temperature and humidity sensor is suitable for industrial environments, HVAC systems, agriculture, warehouses, greenhouses, and storage areas.
