How to make the induction light less sensitive?
2 Answers
The sensitivity can be reduced by decreasing the gain of the Doppler signal amplification circuit inside the induction light. Here is some extended information about radar induction lights: 1. Doppler module: The Doppler module consists of a microwave transistor, resistors, capacitors, and a printed antenna. During operation, it can emit microwave signals into the surrounding space. The Doppler signal processing circuit is generally composed of a low-power BISS0001 dedicated IC, which determines the sensitivity and delay time of the induction light. For convenient adjustment, radar induction switches usually come with potentiometers for adjusting the sensing distance and delay time, with corresponding windows on the casing. 2. Radar induction switch: The radar induction switch can be used for induction control of incandescent lamps, fluorescent lamps, and LED lights, with a control distance of up to 8m. This type of radar induction switch includes light control and allows adjustment of the induction control distance and delay time.
I've encountered issues with overly sensitive automatic headlights before, often due to dirty ambient light sensors or incorrect settings. In vehicles, this can cause headlights to activate unnecessarily frequently - like during cloudy weather or when passing under bridge shadows. The simplest first step is cleaning the sensor (usually located above the windshield or near the rearview mirror) with a soft cloth. If adjustable, access the headlight sensitivity settings through the infotainment menu and reduce the activation threshold so lights only turn on in darker conditions. Regular cleaning prevents many minor issues, as excessive activation can distract drivers and strain the battery. If cleaning and adjustments don't help, it likely indicates sensor aging or electrical faults requiring professional inspection. While automatic headlights are beneficial, excessive sensitivity creates problems - timely calibration is crucial.
