What Causes the Slow Response of Sensor Lights?

[VanMarcus]

It may be due to design reasons. To prevent frequent activation of headlights caused by short-term obstructions like tree shadows, the design intentionally incorporates a delay of about ten seconds before the headlights automatically turn on. If you find the visibility too poor when entering a tunnel before the headlights have time to activate, you can manually turn them on. Below is additional information about radar sensor lights: 1. Doppler Module: The Doppler module consists of a microwave transistor, resistors, capacitors, and a printed antenna. During operation, it emits microwave signals into the surrounding space. The Doppler signal processing circuit is usually composed of a low-power BISS0001 IC, which determines the sensitivity and delay time of the sensor light. For easy adjustment, radar sensor switches generally include potentiometers for adjusting the sensing distance and delay time, with access windows on the casing. 2. Radar Sensor Switch: Radar sensor switches can be used for the sensor control of incandescent, fluorescent, and LED lights, with a control range of up to 8m. These radar sensor switches feature light control and allow adjustment of the sensing distance and delay time.
