Grove - Light Sensor

Grove - Light Sensor
Sold Out
£ 8.99

Light Sensor for the GoPiGo & GrovePi System. Light sensors detect light intensity, allowing you to program your GrovePi or GoPiGo robot car to react to changes in light. Program your GoPiGo car react to light the way a bat would, or use the GrovePi to take a picture of the sunrise every morning to see the difference over the course of the year.

Please Note. This product uses a Grove Sensor Connector, and requires a compatible Grove Board for use on the Raspberry Pi.

Please Note. This package includes the Sensor & Grove Cable Only. Mounting hardware & Servo Package for use on the GoPiGo is sold separately.

The Grove Light sensor module uses GL5528 photoresistor (light dependent resistor) to detect the intensity of light in the environment. The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light (i.e based on resistance value). The output signal from this module will be HIGH in bright light and LOW in the dark.

This module can be used to build a light controlled switch i.e switch off lights during day time and switch on lights during night time.
