Advanced Sensing Technology: Equipped with a high-grade CMOS SHT30 sensor, this RS485 temperature and humidity transmitter 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 build makes it dust, rain, and snow resistant. RS485 Modbus Protocol Compatibility: This sensor features an RS485 output, supporting the Modbus-RTU protocol, which enhances transmission stability over distances up to 1200 meters. It features a wall-mounted design and operates with a power supply ranging from DC 5 V to 36 V. Precision Measurement: Temperature accuracy is ±0.3°C within the 0°C to 60°C range and ±0.5°C outside this range. Humidity accuracy is ±2% RH within the 10% to 90% RH range and ±5% RH outside of it. Data is collected every 10 seconds. User-Friendly Configuration: Configuration is performed via DIP switches for address setting, supporting easy identification and integration of multiple sensors. The system offers 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 has an IP54 rating and is suitable for industrial sites, HVAC systems, agriculture, warehouses, and greenhouses.
