EXPERIMENT 3
: LIGHTS ON A SENSOR
15
Energy for Your House
15
Operating the
LEDs with light
sensor
You will need
– Assembled model house
– Charged batteries in battery station
– LED set with light sensor
Here’s how
1. Plug the cable running out of the house into
port 2 on the battery station. The switch on
the battery station must be in the top
position.
2. Completely darken the room where the
house is located. Casting a shadow on the
house is not enough.
3. Observe the two LED lights in the lamp and
behind the screen.
When it gets dark around the house, the LEDs light up. For this to
happen, the light sensor on the inside wall of the house must be able to
detect darkness. This light sensor is a photodiode, which changes its
electrical conductivity depending on light. When light hits it, it blocks
the flow of electricity and the lights stay o.
Similar but more complex technologies are used in houses and
apartments so that, for example, lighting is switched on only when it is
needed. This saves energy, because like your LED lighting, lamps and
lighting require electricity.
