BOSON Light Sensor i4

SKU: BOS0004

This light sensor, based on environmentally friendly PT550 photodiode, can be used to detect the intensity of the ambient light by converting optical signals to electrical signals with photodiode. It features analog voltage output that is directly proportional to the ambient light. Besides, the sensor works well with maincontrollers such as micro:bit and Arduino, suitable for not only Mind+ and makecode graphical programming but also non-programming projects.
