Project Description

I need a prototype design and 5 pcs. of demo units of the follwing:

Light Swith with adjustable light sensor (See attachd word file).

The switch is intended to turn a normal 220V light bulb on and off based on the amount of ambient light surrounding the switch.

The switch must works as follows:

When the amount of light detected by sensor is high, then the switch is off
When the amount of light detected by sensor is low, then the switch is on.
The level of light amount triggering a switch between the two states must be adjustable by potentiometer or similar.

The design should take overall life time in to consideration.

The switch must be encased in sprinkle proof housing (IP65).

Time plan required.
