Arduino LilyPad is a sensor specifically designed for use with Arduino Lilypad mainboard and can be emulated perfectly on any project in robotics. Grove - 4 pin Female to Grove 4 pin Cable (5 Pcs) Add to Cart. Also find here related product comparison. The digital output has a trim potentiometer that can be used to set a trigger light level. The VMA407 is a light sensor module to allow you to measure light levels using an LDR to produce an output analogue voltage that varies with the light level. There will be two sets of 8 bit data. 2 when measuring fluorescent light versus incandescent. Remember: Outputs from sensors are inputs to the Arduino. Right now in the circuit diagram it is configured as a Shadow Detector, that means the LED will turn on when we show a bright light over LDR. For this purpose, we will connect a LM35 and a light sensor for our weather station, which will measure temperature and intensity of light in real time and using LabIEW.
