TECH STEROWNIKI bedrade temperatuur- en vochtigheidssensor wit C-S1M

The TECH STEROWNIKI C-S1M is a professional wired temperature and humidity sensor designed for precise environmental monitoring in building automation, HVAC, and industrial control systems. Utilizing the Modbus RTU (RS485) communication protocol, it provides reliable digital output for integration with controllers and data loggers. The sensor features a robust ABS plastic housing in white, suitable for wall mounting in indoor environments.

Advantages

High accuracy with ±0.5°C temperature and ±3% RH humidity tolerance ensures reliable data. Wide operating voltage range (9-30V DC) and low current consumption (max 15 mA) make it energy-efficient and versatile. Configurable Modbus address (1-247) and baud rates (9600-115200 bps) allow flexible integration into existing networks.

Suitable for

• Building management systems (BMS)
• HVAC control and monitoring
• Greenhouses and agricultural climate control
• Server rooms and data centers
• Industrial automation

Recommendations

For optimal performance, use a shielded twisted-pair cable for RS485 communication and ensure proper termination. The sensor should be installed in a location representative of the environment to be monitored, away from direct sunlight, heat sources, and drafts. Regular calibration is recommended for critical applications.
