Motion control sensor for arm use with various sensor controllers (a010110, a010126, a010106). It can turn on and off lighting, adjust brightness with a wave of the hand through non-metallic materials such as wood, acrylic, plastic, and glass. Low-voltage 5V DC power supply with a 5V level or PWM output signal. Wave your hand, once the light turns on, wave again and the light will turn off. Detection distance ≤ 5 cm. 1s for light off, 2s for light off. Logarithmic dimming curves. Hand stop moment can be set with or without dimming. 3 levels of PWM output frequency can be set (500 Hz/2 kHz (default)/4 kHz). Sleek design, no need to cut a hole.
