5V Light Detector analog / digital ‘Flying Fish – MH Sensor Series”

Took me a while to find the purpose of this little device I had in the mail recently. it’s a light detection sensor, which I connected to the arduino nano to test its functionality. it servs the amount of light from 0 (very bright) to 1024 (very dark) using the analog pin. To use this device with the ESP8266 you’ll probably need to adapt the voltage and transform it between 0-1V.  But for now, it works fine costing around 2 EUR 🙂

Output looks like this (analog):
