However, the remaining power and voltage of the lithium battery are highly nonlinear. We can only roughly judge whether the battery is full or almost empty according to its voltage. The Gravity I2C 3.7V Lithium Battery Fuel Gauge employs Gravity I2C interface, ultra-low operating current, and real-time tracking of the relative state of charge (SOC) of the battery through Maxim's patented algorithm, eliminating the need for full-to-empty relearning and offset accumulation errors. Plug and play to accurately measure the voltage and remaining power of the battery. The module also features as a low battery power alert interrupt function. When the battery power falls below specified threshold, the ALR pin generates a falling pulse to trigger the external interrupt of the controller.\u003cbr\u003e\u003cbr\u003eYou will find it a great help to estimate the battery life by learning the power consumption of the system with this module. In the solar powered projects, it helps to record the status of the battery power change in a day or even months, which benefits to understand the power balance of charge and discharge of the solar system.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv\u003e\n\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0563\/DFR0563-Arduino.jpg\" original=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0563\/DFR0563-Arduino.jpg\"\u003e\u003cbr\u003e\u003cbr\u003eGravity: 3.7V Li Battery Fuel Gauge Connection Diagram (\u003ca href=\"https:\/\/www.dfrobot.com\/product-838.html\"\u003eArduino UNO\u003c\/a\u003e)\u003cbr\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0563\/DFR0563-Raspberry.jpg\" original=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0563\/DFR0563-Raspberry.jpg\"\u003e\u003cbr\u003e\u003cbr\u003eGravity: 3.7V Li Battery Fuel Gauge Connection Diagram (\u003ca href=\"https:\/\/www.dfrobot.com\/product-1419.html\"\u003eRaspberry Pi 3B\u003c\/a\u003e)\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eProjects: \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-1054.html\"\u003eMake a shiny dice for monitoring battery capacity\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eThe materials you may need:\u003c\/div\u003e\n\u003cdiv\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1734.html\"\u003eGravity: I2C 3.7V Li Battery Fuel Gauge\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1075.html\"\u003eBeetle - The Smallest Arduino\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1754.html\"\u003eSingle Sided ProtoBoard ( flexible PCB )\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv\u003eLED Lamp Beads  ×21\u003c\/div\u003e\n\u003cdiv\u003eCrystal Epoxy Resin and metal complex dyes\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch4\u003eFEATURES\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eMaxim's Patented Algorithm, accurate voltage and remaining power readings of lithium battery\u003c\/li\u003e\n\u003cli\u003eNo Full-to-Empty Relearning Process, No Offset Accumulation Errors, Plug and Play\u003c\/li\u003e\n\u003cli\u003eWide Input Voltage, Compatible with 3.3V and 5V Controllers\u003c\/li\u003e\n\u003cli\u003eProgrammable Low Power Alert Interrupt Threshold\u003c\/li\u003e\n\u003cli\u003eBattery Reverse Connection Protection\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eAPPLICATIONS\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eSolar Weather Station, Street Light\u003c\/li\u003e\n\u003cli\u003eLithium Battery Charger\u003c\/li\u003e\n\u003cli\u003eRobotics\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eSPECIFICATION\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eInput Voltage (VCC): 3.3V~6.0V\u003c\/li\u003e\n\u003cli\u003eBattery Input Voltage (BAT IN): 2.5V~4.2V\u003c\/li\u003e\n\u003cli\u003eBattery Type(BAT IN): 3.7V Li-polymer\/Li-ion battery\u003c\/li\u003e\n\u003cli\u003eOperating Current: 50 uA\u003c\/li\u003e\n\u003cli\u003eInterface: Gravity I2C (logic level: 0-3.3V)\u003c\/li\u003e\n\u003cli\u003eDimension: 22.0*30.0mm\/0.86*1.18 inches\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003ePROJECTS\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cb\u003eProject 1.\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/community.dfrobot.com\/makelog-312083.html\" target=\"_blank\"\u003eSmart Compost Bin Monitoring System -Based on 4G IoT and SHT20\u003c\/a\u003e\u003c\/b\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cb\u003eIntroduction:\u003c\/b\u003e\n\u003cp\u003eThe other day my friend asked me to help him remake his compost bin, he wants a device that allows him to remotely get the real-time temperature and humidity inside.
