Photoresist Sensor Relay Module Optically Controlled Delay Adjustable Switch no Light Induction 5V12V24VItem NO.: HCW-M417

Photoresistor Sensor Relay Module

Light Control Delay Adjustable Switch

Product Information:

The new light-controlled delay module is equipped with a multi-turn precision adjustable potentiometer. The sensitivity and delay can be accurately adjusted to the appropriate range, and the application is stable. Please note that the power supply has two versions of 5V.12V when shooting.

When the module senses dark light or no light, the relay is closed!!!

There are two types of sensor probes: photosensitive resistor and photodiode type. The default type is photosensitive resistor type. If you need photodiode, please shoot the photodiode probe separately.

Product Use:

Automatic light detection, brightness detection, through the potentiometer can adjust the detection brightness valve point, and has its own relay and delay function. When the light is darker than the adjusted brightness of the potentiometer, the relay switch automatically turns on, and can do various light detection alarm, light control delay switch, brightness detection switch, can control various street lights, automatically turn on at night, automatically turn off during the day, and auto headlights, stage lights, LED lights, Traffic light detection switch, the product has the function of adjustable delay and light sensitivity, and the light sensing does not flicker.

Product Introduction:

1. The product is controlled by imported chips, with stable and reliable quality;

2. The power supply part has diode protection, filter capacitor, anti-interference capacitor and 7805 voltage stabilizing chip, which can provide stable voltage and prevent the module from burning when the power supply is connected reversely;

3. The product is equipped with precision adjustable potentiometer to better adjust the sensitivity and delay time;

4. There is power indication and relay closing indication;

5. The module is equipped with high-power relay, which can control 10A current load;

6. The module is equipped with a 50cm long photoresist sensor;

7. The module has a delay and can adjust the delay time to solve the flicker problem of the relay 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. Maximum power consumption 72mA 45mA 28mA

4. Relay load capacity: 250V 10A (AC) 30V 10A (DC)

5. Ambient temperature:<80 ℃

6. Delay range: plug in S2. The delay is adjustable for 1-20 seconds, and without S2, it is adjustable for 1-200 seconds.

Product Use Method:

1. Product wiring: connect DC+and DC - to the corresponding DC power supply (for example, 5V DC power supply). If the relay controls 220V AC or is different from the power supply of the module, please follow the first connection method. If the relay controls the same power supply as the power supply, the second connection method can be simpler;

2. Plug in the sensor probe and connect the DC power supply (ensure that the voltage meets the requirements and the polarity cannot be reversed);

3. Time delay adjustment method: the time range of plugging in the jumper S2 is 1-20 seconds, and that of not plugging in is 1-20 seconds. The clockwise adjustment time of the delay potentiometer will be longer, and the counterclockwise adjustment time will be shorter. When adjusting the sensitivity, be sure to adjust the delay to the shortest delay time of about 1 second (counterclockwise adjustment 10 turns left and right);

4. Adjustment of sensor sensitivity: adjust the sensitivity potentiometer when the probe is in a light environment. If you cover the sensor head with your hand, the relay will close. If you release it with a delay and the relay is disconnected, the module will have the sensing function. If you want to adjust the sensitivity, adjust it clockwise, the more sensitive the sensing will be. You can adjust it to start the relay when the light is dim, and adjust it counterclockwise, the more it will be adjusted to not close when the light is bright.

5. Adjustment method of delay time: the delay time will be extended by clockwise adjustment.
