A Power Indicator Battery Detection Module is a gadget that detects the charge level in a battery and displays the remaining power level to the user.
It often contains a voltage divider circuit that can convert the battery voltage to a level that a microcontroller or other device can read, as well as an indicator circuit that may display the remaining power level using LEDs or other visual means.
The Power Indication Battery Detection Sensor Module you indicated most likely has four LEDs or other indicator lights to indicate different degrees of remaining power, such as a green LED for full power, a yellow LED for medium power, and a red LED for low power. Onboard high precision voltage detection chip and power supply voltage chip.Four onboard battery indicator light-emitting diodes (leds).
Three kinds of color display, red, yellow, green, representing 20%, 50%, 80%, 100% of the battery. Set aside all the batteries testing interface and the two positioning hole. By Removing the LEDs and extending their connections to arduino, this module can also be used with all arduino boards. PCB Size: 22.2(mm)x17.2.(mm)
