• Use in HVAC adjustment, ventilation control, or plant care setups

Key specifications

• Measurement types: ambient temperature and relative humidity
• Form factor: freestanding wired sensor designed for indoor use
• Weight: approximately 150 g
• Placement: designed for flat-surface placement in rooms

How to use

Place the Sonoff THR316D on a stable, flat surface away from direct heat sources, sunlight and drafts to ensure representative readings of the room environment. Connect the sensor’s wired interface to the compatible Sonoff control unit or designated input following the control unit’s installation instructions. Once connected, verify that the host device recognizes temperature and humidity inputs and configure any automation rules, alerts or data logging as required through the host interface.

Recommendations

For accurate measurements, position the sensor at typical breathing height in living spaces and avoid mounting near radiators, air vents or windows. Regularly inspect the connection to the host unit to ensure stable wired communication and follow the host system’s guidance for calibration or offset adjustments if small discrepancies appear over time.
