LTC4150 Current Power Sensor Detection Module is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used.
When used effectively and if you start with a full battery, you’ll always know exactly how much of it is left! At one end of the Coulomb Counter, Breakout is headers labeled IN and OUT. Connect your battery or power supply to the IN header or JST battery connector (they’re identical), and connect the OUT header to your project. At the other end of the Coulomb Counter, you’ll find a header with six pins.
These are the pins you’ll need to connect to your microcontroller and include VIO (Voltage Input), INT (Interrupt), POL (Polarity), GND (Ground), CLR (Clear), and SHDN (Shutdown). Simply install this breakout out between your power source and your circuit, that way all the current your circuit uses needs to pass through the Coulomb Counter to be measured.
