Product Description
The Simple Light Sensor Board is a versatile solution for adding light detection to your electronics projects. It’s a complete module that provides both analog and digital outputs, giving you the flexibility to create a wide range of applications. Whether you’re building an automatic lighting system, a plant-monitoring device, or a smart home alarm, this sensor board provides the reliable light detection that every maker needs.
The onboard LM393 comparator and adjustable potentiometer make this board perfect for creating precise light-activated triggers. You can easily set a specific light threshold for the digital output, allowing you to trigger an action when the light level crosses a certain point. This is ideal for beginners who want a simple on/off signal, as well as for advanced users who need to fine-tune the sensor’s sensitivity for their specific application. Perfect for students learning about sensors, hobbyists building interactive projects, or engineers prototyping new devices.
What makes this light sensor board special is its all-in-one design, combining a LDR with all the necessary circuitry on a compact module. This sensor will not give you detailed lux readings, just a simple analog value proportional to the amount of light. As with all our products, it’s open-source, with all design files available for you to modify and adapt. Plus, with our 2-year warranty and technical support, you can be confident in your purchase.

Product usage tips
Connect the GND and VCC pins on the breakout board to your Dasduino to get the results. Given the rugged nature of the light-dependent resistor, the simple light sensor is suitable for dirty and rough terrains.
The simple light sensor can be used for various practical automated projects. They range from simple, such as light intensity meter, to very complex, like a burglar alarm. Perfect for those ideas where you want to avoid manual input.
If you’re experiencing issues when using the sensor, check if all components are connected properly. Go through your wiring on the breadboard once more. If everything is connected as it should be, go through the code again. There’s a chance some bugs are stopping the program from functioning.
