Odometers are extremely useful for cars, they tell you how far you have gone, wouldn’t it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defind as, to put it simply, one amp for one second. This breakout 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 are 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.

里程表是汽車非常有用的,他們會告訴你,你已經走了多遠,那豈不是如果你能夠有,做同樣的電流的設備很好嗎?該LTC4150 SparkFun庫侖計突圍這裡成為您當前的里程表。如果你想知道:一個庫侖defind的,簡單地說,一是耳放一秒。這種突破能夠持續監控您的傳感器使用的電流,能夠把它加起來,並已使用的安培小時一定量每次都會給你一個脈衝。當有效使用,如果你開始一個完整的電池,你總是知道到底如何呢還剩下多少!
在庫侖計突圍的一端是標記IN和OUT頭。電池或電源連接到頁眉或JST電池連接器(它們是相同的),而OUT頭連接到您的項目。在庫侖計的另一端,你會發現有六針的頭部。這些都是你需要連接到您的微控制器引腳,包括VIO(電壓輸入),INT(中斷),POL(極性),GND(地),CLR(清除),和SHDN(關機)。只需安裝這個突破你的電源和你的電路,這樣所有的電流的電路使用需求都可以通過庫侖計進行測量的。
