Need a device to sense light? We have the Grove – Light Sensor v1.2 for you. Now you can measure light levels with higher reliability and sensibility. It is an updated version of Grove – Light Sensor 1.0. You can use it as a light-controlled switch i.e. switch off lights during day time and switch on lights during night time.
The resistance of light sensor, also known as the Light Dependent Resistor (LDR) decreases when the ambient light intensity increases. However, the change in resistance due to ambient light is not linear; in low-light conditions, small changes in luminescence cause relatively large changes in resistance (or output voltage), but in well-lit conditions, changes in luminescence cause only small changes in resistance.
A dual OP-AMP chip LM358 on board produces voltage corresponding to the intensity of light (i.e. based on the resistance value). The output signal is an analog value. The brighter the light is, the larger the value will be. The output electrical signals can be converted to different ranges (It depends on the Analog-to-Digital-Converter on your controller board. For example, it can output 0-255 for an 8-bit ADC). It integrates a high-sensitive and reliable phototriode GL5528. Just like other grove modules, you can interface this sensor with Grove port which can save a lot of work in the wiring.
For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before using the product. This is a suitable product for not only Grove users but also all electronic enthusiasts. So, why wait? Buy now!
Warning: The light sensor value only reflects an approximated trend of light intensity, it DOES NOT represent the exact Lumen count.
