描述

SparkFun Coulomb Counter Breakout – LTC4150 庫倫計數器模組 鋰離子電池及電池電量計

里程表對汽車來說是非常有用的，他們會告訴你你已經走了多遠，如果你能夠有一個相同的電流設備，這不是很好嗎？LTC4150 SparkFun庫侖計數器突破在這裡是您當前的里程表。如果你想知道：一個庫倫被定義為簡單地說，一個放大器一秒。這個突破是能夠不斷監測你的傳感器正在使用的電流，能夠加起來，並會給你一個脈衝，每次使用給定的安培小時數。當有效地使用，如果你從一個完整的電池開始，你將永遠知道它剩下多少！

庫侖計數器分線的一端是標記為“輸入”和“輸出”的標題。將電池或電源連接到IN接頭或JST電池連接器（它們是相同的），並將OUT接頭連接到您的項目。在庫侖計的另一端，你會發現一個六針的頭。這些是您需要連接到微控制器的引腳，包括VIO（電壓輸入），INT（中斷），POL（極性），GND（地），CLR（清除）和SHDN（關斷）。只需在電源和電路之間安裝這個突破，這樣你的電路使用的所有電流就需要通過庫倫計數器進行測量。

SparkFun Coulomb Counter Breakout – LTC4150

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.
