A Coulomb Counter is a device to measure the current that your devices or sensors are using. The coulomb symbol: C is the International System of Units of electric charge. It is the charge symbol: Q or q transported by a constant current of one ampere in one second: 1C=1A•1s. If you are charging a battery, you can use this module to monitor the charging process.
Highlighted Features
- A precision coulomb counter integrates current through a sense resistor between the battery’s positive terminal and the load or charger
- This module measures the number of amp-hours that have been used, if you use a fully charged battery, you can test the amount of battery you have used just like the remaining battery shown in your phone
