Adafruit 1384 ga1a12s202 log scale analog light sensor
Adafruit analogue light sensor breakouts adafruit 1384 the adafruit ga1a1s202 log scale analogue light sensor is very simple sensor to use just add power and then monitor the analogue output most light sensors have a linear response to the light intensity which means that they can be quite insensitive to low light levels and then max out at high light levels this sensor on the other hand has a logarithmic response which means that it is more sensitive in low light conditions when small cha
