auto intensity control of street light using arduino. for example, the intensity of light is low in the evening and it starts increasing until 8pm after 8pm the light glows at full intensity and this intensity will not change. it glows on full intensity until 12am and intensity starts decreasing after 12am, and the lights are fully turned off after 6am. this approach saves about 30 percentage energy.
language, should be provided with the solar street lighting system. the following minimum details must be provided in the manual basic principles of photovoltaics. a small write up (with a block diagram) on solar street lighting system its components, pv module, battery, electronics and luminaire and expected performance.
you may link to these circuits, but please do not copy them to any website. there are many solar powered garden lights available. most of the devices offered at the home improvement stores have very poor performance. their batteries are too small, the light launched is weak and the solar
volts with two solar panels and two batteries wired in parallel, your volts remain the same at 18 volts (panels) and 12 volts (battery bank) so you will only be able to charge a 12 volt battery bank and thus power up to 12 volt appliances.
automatic staircase lights using pir sensor and relay. this automatic staircase light circuit can be easily explained. whenever pir sensor detects any body movement, its output pin becomes high, which applies the triggering voltage to the base of the transistor, transistor get on, and current started flowing through the coil.
