Module using the instructions: 1, photoresistors module is most sensitive to ambient light, generally used to detect the brightness of the ambient light. 2, the module when the ambient light is darker than the threshold value is set, the relay is energized, the common terminal and the normally start is turned on, when external ambient light is brighter than the set threshold value, the relay is switched off, the common terminal and the normally closed end connected. 3, the public side, normally open, normally closed three ports, the equivalent of a dual-control switch, relay coil power, public end and often the beginning of conduction, radio, public end normally closed terminal conduction. Product Description: Stable version of the module is 12V supply, without delay function, pull relay matt, bright disconnect Package Included: 1xPhotoresistor Plus Relay Module ## Features - Imports of high-performance quality delay chip design , safety. - Protection against power reverse protection diode. - Supply voltage: 6-14V ; Current : > 500mA ;The maximum load of the relay: 220V 10A or 30V 10A ; 1-190 seconds delay time. - Product life and aging tests, automatically pass off time is adjustable timing precision. - Light detection and brightness detection, detection can be adjusted via potentiometer brightness valve point comes relays, and do all kinds of brightness detection switch, you can control all kinds of street lights or car lights automatically turn on at night, during the day and automatically turns off and car supplies control and automation equipment. ## Images ![KNACRO 12V Light Control Switch The Photoresistor Plus Relay Module The Light Detection Switch Photosensitive Sensor - Image 1](https://m.media-amazon.com/images/I/31Ho7JnV-tL.jpg) ![KNACRO 12V Light Control Switch The Photoresistor Plus Relay Module The Light Detection Switch Photosensitive Sensor - Image 2](https://m.media-amazon.com/images/I/41si9oYVVML.jpg) ![KNACRO 12V Light Control Switch The Photoresistor Plus Relay Module The Light Detection Switch Photosensitive Sensor - Image 3](https://m.media-amazon.com/images/I/41QiUjEi3cL.jpg) ![KNACRO 12V Light Control Switch The Photoresistor Plus Relay Module The Light Detection Switch Photosensitive Sensor - Image 4](https://m.media-amazon.com/images/I/31uMLAIosGL.jpg) ![KNACRO 12V Light Control Switch The Photoresistor Plus Relay Module The Light Detection Switch Photosensitive Sensor - Image 5](https://m.media-amazon.com/images/I/31dDu9BoPmL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/102008976-knacro-12v-light-control-switch-the-photoresistor-plus-relay-module](https://www.desertcart.pl/products/102008976-knacro-12v-light-control-switch-the-photoresistor-plus-relay-module) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
