- 4x BPW34 photodiodes aka solar cell
(plastic diodes, resistant to damage against glass solar cell)
- Up to 10F supercapacior
(You can use bigger capacity but 10F is optimal for charge in one sunny day)
- 4 hours operation in night depends on intensity
- Auto night on
- step up converter effective use all stored energy, discharge scap until 0.3V !!!!!!
TWO operation modes ...
1. Night mode - output is activated in night
2.Pulse mode - output is activated after capacitor is charged to startup voltage
