Description

As an updated version of Grove - Light Sensor 1.0, the Grove - Light Sensor v1.2 is also designed to measure light levels, but with greater reliability and sensitivity. It is an analog module that delivers different electrical signals that can be converted in different ranges (depending on the analog-to-digital converter of your controller board). For example, it can output 0-255 for an 8-bit ADC. It integrates a highly sensitive and reliable phototriode, and like other Grove modules, it interfaces with the Grove port, saving a lot of cabling work.
