Scope of this module:

Mainly used for battery (9V or 12V) voltage monitoring, simple and practical, with sound and light alarm prompts.

Product Features:

After the battery is under voltage, the buzzer will make a sound of "di di di", and the red LED indicator will light up at the same time. When the battery voltage rises above the set value by itself, the buzzer will stop alarming.

Brief introduction:

1. Size: 2.9CM*3.0CM, main chip: LM358;

9V battery: When the battery is over-discharged (battery voltage is lower than about 8V), the red indicator light will be on and the buzzer will sound, realizing sound and light alarm, so as to realize the control of the battery discharge state, to prevent the battery from being over-discharged and damaging the battery;

12V battery: When the battery is over-discharged (battery voltage is lower than about 10.4V), the red indicator light will be on and the buzzer will beep, and the sound and light alarm will be realized, so as to realize the control of the battery discharge state, so as to prevent the battery from being over-discharged and damaging the battery;

Advantages:

1. With sound and light alarm, it is clear whether there is a protective effect;

2. The module input has reverse connection protection, and the polarity of the input power supply will not be burned out. But there is no overvoltage protection, if the input exceeds 15V, the chip on the module will burn out.
