Differs from the last version, the Grove - Light Sensor (P) v1.1 uses the LS06-S phototransistor as a replacement of the traditional Light Dependent Resistor (LDR) sensors. The LS06-S light sensor has much more linear analog output conforming to illuminance, which ranges from 0 to the supplying voltage (normally 5V). A value equals to the supplying voltage can be detected when it’s exposed to daylight, and it gives 0V when you covered it with your hand.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
It will be appreciated if you can help us improve the documents, provide more demo code or tutorials. For technical support, please post your questions to our forum.
