Outdoor Wall Light Lamp LED PIR Infrared Motion RF Sensor Detector AC85V~260V
US$7.70 US$9.24

Q: Does the sensor use a relay (clicks) or a triac (completely silent) to switch the load?

I wanted to wire several PIR motion sensors together for one main lighting, so I couldn’t use a sensor that uses a semiconductor for switching (triac). The sensor works perfectly. In contrast to the pictures shown above, there aren’t any visible screws on the bottom and thus the device cannot be taken apart, e. g. for replacing the rather cheapo wires or other repair jobs. There is a silicone sealing between the adjustable parts of the mounting arm. The sensor consumes 0.9 Watts when switched on and off. By using a switching power supply instead of a capacitive power supply the power consumption could be reduced dramatically in stand-by mode. All in all it is a decent device.

Patternman Brown is phase, blue is neutral and red is the switched phase of the load!

The standoffs are satisfying. The dimensions are complient. The adhesive pads though don’t seem to be genuine a 3M product as claimed in the description (there are no 3M logos on the protective foils either), as their adhesive power is rather poor. So, double-check if the standoffs can secure your PCBs sufficiently during transport or when positioned vertically, and replace the pads if necessary.
