Rayzeek RZ021 壁挂式运动传感器，美国标准

We are renovating a house we purchased and I plan to build a walk in closet and use this as a motion switch for the lighting. I like that not only is it motion controlled but has an on off button for manual control if needed. Happy with it so far.

It works well. Easy to install and set it up.

The wiring of Neutral Wire is the one I would choose for ease of installation (no ground requirement) and ease of adjustment for timing, plus easy over-ride, and good sensitivity.

Excellent switch. Works precisely as described, and is easy to program.

This motion sensor switch solved my biggest headache: someone (especially me!) constantly forgetting to turn off lights in the bathroom, kitchen, and balcony! Since installing it, those worries vanished. Its core strength is smart energy saving – it only works when needed, minimizing power waste. Eco-friendly and cost-effective!

Real-world performance is excellent:

Reasonable detection range: Covers entry areas effectively without false triggers from afar or failing to activate up close.

Fast response: Lights turn on almost instantly upon entering the detection zone – no annoying delays.

Accurate ambient light sensing: Doesn’t turn on unnecessarily during bright daylight but activates reliably at night or in low light. Very smart logic!

Easy installation: Replacing my old switch was smooth (recommend basic electrical knowledge or professional help).

Biggest surprise? It even detects my cat walking by (though not officially advertised for pets) – now I can see where he’s wandering at night! After weeks of use, the electricity savings are a bonus; the real win is peace of mind! No more checking every room to see if lights are off. Technology improves life – this sensor switch deserves a 5-star rating!
