Grove Light Sensor


This sample application gets the output of the grove light sensor and prints it to the console, in units of lux, once every second.


To use this sample, the following hardware is required:


The easiest way to connect the sensor is to connect it to a Grove shield on a board that supports Arduino shields. Provide a devicetree overlay that specifies the sensor location. If using the overlay provided for the sample, the sensor should be connected to A0 on the Grove shield.

Building and Running

Build and flash the sample as follows, changing nrf52dk_nrf52832 to your board:

west build -b nrf52dk_nrf52832 samples/sensor/grove_light
west flash
