Microduino-Lightness

The product number of Sensor-Light-A1 is: MSDT42

Sensor-Light-A1 is a photosensitive brightness detection sensor module.


The light sensor transforms the light signal into electric signal with the photosensitive resistance. Its sensitive wavelength is near that of the visible light, including the infrared and the ultraviolet.

Description of the Sensor Pin

Light A1 Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Analog Input
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.
