At the discount shop here in the UK I bought an Ambi Pur "Light Sensor". This is a dispenser for air fragrance with a light operated switch so it operates only in daylight.
This is it:
Mine didn't come with a fragrance container to try, so does anyone know if the brown-coloured collar inside the dispenser is simply an electromagnet (which then presumably tugs open some part of the fragrance container). It doesn't seem to have any moving parts.
What is the voltage of the two electrical leads which go to operate the brown collar?
