2-Ch 5V relay Board with optocoupler raspberry pi mounting the sensor under a

mounting the sensor under a protective overhang to minimize direct rain impact

The modular arm design allows replacement of a single damaged arm for approximately 20-30 percent of the frame cost

and gas detection payloads for power line inspection

Regular calibration checks every 6-12 months help ensure continued accuracy and allow early detection of sensor degradation
