As soon as the battery voltage falls below the set threshold level, the left transistor is no longer able to conduct. This situation instantly switches ON the right hand side transistor, enabling the LED to illuminate. The LED switches ON and provides the required indications of a low battery warning.
This low battery indicator circuit is used with a programmable unijunction transistor (PUT), since the threshold characteristics of the UJT could be effectively defined, and can be designed to flash a connected LED indicator. The PUT (Q1) is configured like a relaxation oscillator circuit.
A simple battery can be made by pushing a screw (best if it is zinc-coated/galvanised) and a piece of copper into a lemon and connecting these two electrodes using wires to the device you want to power. This cell can produce enough power to run an LCD clock/watch.
Gather your materials. For this battery, you will need one unopened can of soda (any type will do), one plastic cup (6 to 8 ounces), and one 3/4-inch-wide strip of copper that's slightly longer than the height of the cup. In addition, you'll need a pair of scissors, a voltage meter, and two electrical lead wires with alligator clips at both ends.
The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the battery voltage drops below a set threshold the voltage at the base of T2 falls below V be (0.6V–0.7V) turning OFF the relay and disconnecting the load. Formula for Threshold Voltage:
