Photoresistor Sensor Relay Module 12V Light Control Delay Adjustable Time Delay Relay Switch with PotentiometerThe new light control delay module is equipped with multi-turn precision adjustable potentiometers. The sensitivity and delay can be accurately adjusted to the appropriate range. The application is stable. Please note that the power supply has 5V.12V.When the module senses dark or no light, the relay will pull in! !! !!There are two types of sensor probes: photoresistor and photodiode. The default is the photoresistor type. If you need a photodiode, please take a photodiode probe separately.Product Usage:Automatic light detection and brightness detection. The potentiometer can be used to adjust the detection of the brightness valve point. It also comes with a built-in relay and delay function. When the light is darker than the potentiometer, the relay switch is automatically turned on, which can be used for various lights 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 lights detection switch, the product has adjustable delay and light sensitivity Adjustable function, light sensor without flicker.product description:1. The product is controlled by imported chips with stable and reliable quality;2. The power supply has diode protection, filter capacitor and anti-interference capacitor and 7805 voltage regulator chip, which can provide stable voltage and prevent the module from being burned when the power supply is reversed;3. The product is equipped with a precision adjustable potentiometer to better adjust the sensitivity and delay time;4. With power indication and relay pull-in indication;5. The module is equipped with high-power relays, which can control 10A current load;6. The module comes with a 50cm long photoresistor sensor;7. The module has a delay, and the delay time can be adjusted to solve the problem of the flicker of the relay at the critical point of light.8. Module size: 63.5x38.5x18.5mm Module net weight: 28gPerformance parameters:1. Power supply: DC5V DC12V DC24V2.Static current 12mA 15mA 12mA3.Max power consumption 72mA 45mA 28mA4. Relay load capacity: 250V 10A (AC) 30V 10A (DC)5. Ambient temperature: <80 degrees6. Delay range: plug in S2. Delay is adjustable from 1-20 seconds, without S2, adjustable from 1 to 200 seconds.product instructions:1. Product wiring: First connect the corresponding DC power supply to DC + and DC- (such as 5V, then connect to 5V DC power supply). If the relay is to control 220V AC or a power supply different from the module, please follow the first connection method. If the relay is to control the same power supply as the power supply, the second connection method is simpler;2. Plug in the sensor probe and apply DC power (make sure the voltage meets the requirements and the polarity cannot be reversed);3. Delay adjustment method: The time range of plug in jumper S2 is 1-20 seconds, without plug-in it is 1-200 seconds. The delay potentiometer adjustment time will be longer in clockwise and reverse time will be shorter. When adjusting sensitivity , Be sure to adjust the delay to the shortest delay time of about 1 second (adjust around 10 turns counterclockwise);4. Sensor sensitivity adjustment: Adjust the probe in a light environment to adjust the sensitivity potentiometer. For example, when you cover the sensor head with your hand, the relay will pull in. When you let go, there will be a delay and the relay will open. The module has a sensing function. If you want to adjust the sensitivity, adjust the clockwise, the more sensitive the induction will be. When the light is dim, the relay will be activated, and the counterclockwise will be more adjusted. When the light is on, the relay will not close.5. Adjusting the delay time: When adjusting clockwise, the delay time is extended.Wiring method 1: (This type of connection cannot insert the jumper S1, otherwise the module will be burned.) The role of delay in the module: When the light is at the set critical point, the light does not suddenly turn to the dark state, but is slow Slow from bright to dark, if there is no delay, the relay will flicker. When the auto headlight is modified, the relay will also flicker because of the unstable ambient light. After adding the delay, this can be avoided. The occurrence of the problem makes the relay work stably and reliably.
