12v stable version light control switch matte induction photosensitive resistance sensor relay module with extension cable

The new light controlled delay module is equipped with a multi turn adjustable potentiometer, and the sensitivity and delay can be adjusted to the appropriate range for stable application. Please note that the power supply is available in three versions: 5V, 12V, and 24V.

This module sensesWhen the light is dim or absentThe relay is engaged!!!

The sensor probe hasPhotoresistor and photosensitive diode typeThere are two types, the default type is photoresistor type. If you need a photosensitive diode, please take a separate photo of the photosensitive diode probe.

Product Usage
Automatic light detection, brightness detection, adjustable brightness valve point through potentiometer, with built-in relay and delay function. When the light is darker than the brightness set by the potentiometer, the relay switch automatically turns on, and can be used for various light detection alarms. The light control delay switch, brightness detection switch, can control various street lights, automatically turn on at night, automatically turn off during the day, and automatic headlights, stage lights, LED lights, traffic light detection switches for cars. The product has adjustable delay and light sensitivity functions, and no flicker in light sensing.
Product Introduction
1. The product is controlled by a chip, ensuring stable and reliable quality;
2. The power supply has two tube protection, filtering capacitors, interference capacitors, and 7805 voltage regulator chip, which can provide stable voltage and prevent module burnout when the power supply is reversed;
3. The product is equipped with an adjustable potentiometer to adjust sensitivity and delay time;
4. There are power indicators and relay engagement indicators;
5. The module is equipped with high-power relays that can control 10A current loads;
6. The module comes with a 50cm long photoresistor sensor;
7. The module has a delay and can adjust the delay time to solve the problem of relay flicker at the critical point of light.
8. Module size: 63.5x38.5x18.5mm Module net weight: 28g
Performance parameters:
1. Power supply: DC5V, DC12V, DC24V
2. Static current 12mA 15mA 12mA
3. Power consumption 72mA 45mA 28mA
4. Relay load capacity: 250V 10A (AC) 30V 10A (DC)
5. Environmental temperature:<80 degrees
6. Delay range: When S2 is inserted, the delay can be adjusted from 1-20 seconds. When S2 is not inserted, the delay can be adjusted from 1-200 seconds.
Product usage instructions:
1. Product wiring:First, connect the corresponding DC power supply to DC+and DC - (for example, 5V, connect to 5V DC power supply). If the relay is controlling 220V AC or a power supply different from the module, please connect it according to the type. If the relay is controlling the same power supply as the module, the second connection is simpler;
2. Plug in the sensor probe and connect it to the DC power supply (ensure that the voltage meets the requirements and cannot be reversed);
3. Delay adjustment method:The time range for inserting jumper S2 is 1-20 seconds, and for unplugging it is 1-200 seconds. The delay potentiometer can be adjusted clockwise for a longer time and counterclockwise for a shorter time. When adjusting sensitivity, be sure to set the delay to about 1 second (counterclockwise for about 10 turns);
4. Adjustment of sensor sensitivity:Adjust the sensitivity potentiometer of the probe in a light environment. If you cover the sensing head with your hand, the relay will close. If you release it, there will be a delay and the relay will disconnect. The module has sensing function. If you want to adjust the sensitivity, adjust it clockwise, the more sensitive the sensing will be. It can be adjusted to start the relay when the light is dim, and counterclockwise to stop closing when there is light.
5. Adjustment method for delay time:Clockwise adjustment prolongs the delay time.

Wiring method one: (This type of connection cannot insert jumper S1, otherwise it will burn out the module)

Wiring method 2:

The role of delay in the module: When the light is at the set critical point, the light does not suddenly turn into a dark state, but slowly changes from bright to dark. Without delay, the relay will flicker. When modifying the automatic headlights of a car, the relay will also flicker due to unstable ambient light. Adding delay can avoid this problem and ensure stable and reliable operation of the relay.
