Customer:
Can your light sensor have its output active when it’s dark and the opposite for light? Specifically, I need a lamp that turns on when dark and turns off when light. The lamp has a 3.7V battery charged by a solar cell, and uses an LED. I can install a small relay for switching. Do you offer everything needed? I need 10 units.

Dali vaš sezor svjetla može imati izlaz aktivan kad je mrak a obratno za svjetlo. Konkretno imam svjetiljku koja se treba upaliti kad je mrak a ugasiti kad je svjetlo. U svjetiljci je baterija 3,7V; puni se sa solarnom čelijom. Svjetiljka je LED. Mogu staviti mali relej za prekidanje. Takvih trebam 10 kom

Soldered Support:
This sensor requires power via VCC (5V) and GND. At a certain light level it will pull D0 LOW (0V). When there’s no light, D0 will be HIGH (5V).
You’ll need to use a relay module.
Here’s how to connect it to work with your light:
Power (+) -----> 5V (Relay Module)
Power (GND) -----> GND (Relay Module)
Sensor digital output -----> IN (Relay Module)
Relay COM -----> Light (one terminal)
Relay NC -----> Power (+) for light
Light (second terminal) -----> Power (GND)
I’ve worked through the logic: connected this way it should work. If you need the opposite behavior, connect the light to NO instead of NC.
If this works for you, I can forward your details to my colleague who will help you with the order.

ovaj senzor: Jednostavan senzor svjetla Pločica za elektroničke projekte – Soldered Electronics
Treba napajanje putem VCC (5V) i GND i onda će na određenu razinu svjetlosti spustiti D0 na LOW (0V). Ako svjetlosti nema, D0 će biti HIGH (5V).
Trebaš onda koristiti relej: Jednokanalni relej Pločica za upravljanje visokim naponom – Soldered Electronics
Evo kako bi ga spojio da radi sa svjetlom:
Napajanje (+) -----> 5V (Relaj Modul)
Napajanje (GND) -----> GND (Relaj Modul)
Digitalni izlaz senzora -----> IN (Relaj Modul)
Relaj COM -----> Svjetlo (jedan terminal)
Relaj NC -----> Napajanje (+) za svjetlo
Svjetlo (drugi terminal) -----> Napajanje (GND)
Probao sam proučiti logiku paljenja i gašenja ovog, ako se spoji ovako i treba raditi suprotno, potrebno je samo spojiti svjetlo umjesto na NC na NO.
Ako vam je ovo OK, mogu proslijediti mail kolegici koja će Vam pomoći napraviti narudžbu.
