Need an easy way to check the current light level? How about trying the light sensor from the Troyka Module series? It's easy to work with and extremely easy to use - no soldering, no small components, no confusion. You don’t even have to worry about trying to figure out a complicated voltage divider - everything is ready for you!
This module is based on the GL5528 photoresistor. If you use this sensor your device will be able to distinguish day from night, sun from clouds, or even when a shadow passes over. Using the light sensor and a laser module together opens up even more possibilities. For example, you can create a custom alarm system which activates when the laser is broken or maybe an accurate and sensitive photo-trigger for your camera. By adding the LED module you could even make an obstacle sensor. The possibilities are endless.
This sensor from the Troyka Module series can be neatly placed on the front panel of your device, fastened with М3 screws.
The output of the sensor is an analog signal. The sensor output voltage is inversely proportional to the intensity of the incident light.
Connect via the 3-pin jumper cable to receive a signal from the module. The 3-pin jumper cable needed for the connection is included in the kit.
There are several different ways to wire this module:
Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.
Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.
Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
