Relative humidity and temperature sensor DB506-97

embeddedwall-mountModbus

Product overview
DB506-97 humidity and temperature sensor provides accurate, reliable measurements with excellent long-term stability. It features a large dual-line LCD for simultaneous display of temperature and relative humidity or other humidity interpretations. Designed for embedded wall-mounted installation, the sensor offers programmable address, high accuracy and stable performance for real-time multi-point temperature and humidity monitoring and centralized management.

Core advantages

• Industrial-grade communication: Modbus RS485 interface, compatible with various industrial control equipment, instruments and host computers; stable and reliable.
• Ultra-long distance transmission: communication distance up to 1200 meters, enabling remote monitoring and control.
• Flexible networking: supports bus cascading of up to 32 devices for multi-point synchronous monitoring and large-scale centralized management.
• On-site direct reading: large display for intuitive, real-time temperature and humidity reading without additional equipment.

Applications

• Industrial workshops, warehousing & logistics, HVAC systems, intelligent buildings.
• Environmental monitoring, agricultural greenhouses, laboratories and other scenarios requiring multi-point temperature & humidity monitoring.
