Color: Blue 

What is it?

Light sensors measure the intensity of visible light in the surrounding environment.We can use it to determine whether the current environment is bright or dark, and also know how bright or how dark it is.

Grove Zero Series Introduction:

Grove Zero is a set of programmable elctronic building blocks which snap together with magentic connections & are used in conjuction with graphical programming software to achieve creative and functional projects. Grove Zero can be used boths as a tool to foster children's creativty as a classroom tool for STEM education. Learn more about the series here.

If this is your first experience with the Grove Zero series, we recommend that you purchase introductory kits such as the Starter Kit, Car Kit or Bit Kit, which include instructional documentation to help you get familiar with this educational series.

How this module works?

The Light Sensor transforms the ambient light level to a voltage level that can be converted into digital signals and read by the microcontroller for calculating the illuminance in lux. When the light intensity is lower than a certain level, which is called ‘the LOW Threshold’, the sensor detects a ‘DARK environment’. When the light intensity is above a ‘HIGH Threshold’, it detects a ‘LIGHT environment’.

Try to use the LOW/HIGH Threshold to trigger events like turn on the buzzer when there is no light.

You can program the Light Sensor very easily with Codecraft to achieve more creative and challenging projects.
