This 12Vdc battery monitor is a really useful addition to your car or bike. It uses three LEDs to give a visual indication of the state of charge of your car battery.
The red LED indicates that the battery voltage is low, the green LED indicates that it is OK and the yellow LED warns that the battery is being overcharged.
The whole circuit is accommodated on a small PCB measuring just 28 x 44mm and can be fitted easily anywhere in the dashboard. LEDs can be mounted vertically or horizontally on the edge of the board.
The kit can be used to monitor any 12Vdc battery and also makes a good educational kit as it introduces resistors, LEDs, diodes, zener diodes and transistors.Features
