The solar radar sensor bottle lights can still detect and work normally when it is hot, because the radar detection uses the Doppler detection principle to detect obvious moving objects and is not affected by ambient temperature . can work in -10℃~40℃ environment, and some can even work normally at lower or higher temperatures. It is recommended to use a radar sensor for solar induction lights. The above information is provided by Haomei Solar Radar Sensor Bottle Lamp.
I used several models, but it is not about human body detection, but about radar detection. I heard from others that radar detection is more sensitive than human body detection, and everything is fine after using it.
There are pictures and the truth
I hope this can help you.
