Product details

Electro-Fashion Sewable Light Sensor

• A simple light sensor that turns connected components on in low light
• Great for all wearable projects
• Connected purely by conductive thread
• Reqiures a CR2032 coin cell battery (not included)

What can you do with the switched light sensor?
This board contains a light-reactive circuit that will turn on any connected LEDs or other components when the room is dark. You will need a CR2032 coin cell battery to power the circuit. Please note, the coin cell holders contain nickel and should not be used in designs where it will have prolonged contact with skin.

Sew this board and other components into your clothing or fabric using conductive thread. If you have hidden the circuit you may make a small hole for the light sensor itself to peer through, and it will protrude by 2mm. There are no other components on that side of the PCB.

The board also has a built-in switch to safely turn the circuit off when it is not in use. You can extend this circuit by sewing conductive thread into the marked terminals.

Can I assume that the battery only powers the light sensor & that the LEDs have to be connected to a separate power source?

Asked by: Phil
Yes that's correct.
