RHT-SDI12-T6 RH & Air temperature sensor

Integrated Climate Monitoring for Modern Data Networks

The RHT-SDI12-T6 represents the next step in environmental sensing, combining two critical meteorological parameters into one intelligent device. Its digital SDI-12 output ensures high-quality, noise-resistant data transmission over long cable runs, making it superior to analog sensors in complex or large-scale deployment scenarios. The integrated M12 connector guarantees a waterproof and robust connection, eliminating wiring errors and reducing installation time. This sensor is engineered for continuous, unattended operation in demanding conditions, providing reliable data for climate studies, HVAC system validation, and precision agriculture management.

Engineered for Simplicity and System Integration

This sensor is designed to be a core component of a networked monitoring system. The SDI-12 protocol allows multiple sensors to share a single data logger channel, drastically simplifying system architecture and reducing costs. The RHT-SDI12-T6 is available as a standalone unit for integration into custom setups or as part of a complete mast-mounted kit (RHT-SDI-12+SRS+MB-T6), which includes a solar radiation shield (SRS-T1) and mounting bracket (MB-T05) to ensure accurate temperature readings by protecting the sensor from direct solar radiation.

Key Advantages of the RHT-SDI12-T6 Sensor

• Dual-Parameter Digital Measurement: Simultaneously captures highly accurate relative humidity and air temperature data on a single digital output.
• Seamless Network Integration: The standard M12 connector and SDI-12 protocol allow for effortless plug-and-play connection into Delta-T's SDI-12 networks and compatible data loggers.
• Ultra-Low Power Consumption: Draws only 8 mA when active and a mere 24 µA when idle, making it perfect for solar-powered or long-term remote monitoring stations.
• Research-Grade Accuracy: Delivers precise measurements (±2% RH, ±0.1°C) essential for scientific research, environmental compliance, and critical process monitoring.
• Complete Solution Available: Can be purchased with a solar radiation shield and mounting bracket for a ready-to-deploy, professional installation.

Optimal Application and Use

For accurate air temperature readings, it is crucial to mount the sensor within a solar radiation shield (like the SRS-T1) to protect it from direct sunlight and precipitation. Connect the sensor to an SDI-12 compatible data logger (such as the Delta-T GP2) using the 3-meter, 3-wire cable with M12 connector. Ensure the connection is secure and the IP rating is maintained. The sensor requires a 6-12 VDC power supply, which is typically provided by the data logger. Configure the SDI-12 address and data logging parameters through your logger's software to start receiving measurements.
