Serial.println("gauge begin successful!") * Copyright GNU Lesser General Public LicenseĪttachInterrupt(digitalPinToInterrupt(ALR_PIN), interruptCallBack, FALLING) //default alert is 32% It switches the positive connection necessary for common negative circuits. * Use API to config alaram and sleep (please reference to the readme in lib) Properly designed p-channel mosfet module. * Voltage, percentage will be printed via serial. * connect gauge I2C interface with your board (please reference board compatibility) The module prints the battery voltage, the percentage of remaining battery power, and the interrupt alert message through the serial port. Open the serial monitor of the Arduino IDE and set the baud rate to 115200.Open Arduino IDE, upload the following sample code to the Arduino UNO.These two connectors are connected internally in parallel. The battery can be connected to the 2P terminal or JST-PH2.0 2P connector. Connect the module to the Arduino according to the connection diagram.Read Battery Voltage, Remaining Power and Set Low Power Interrupt Alert Interface: Gravity I2C (logic level: 0-3.3V).Battery Type(BAT IN): 3.7V Li-polymer/Li-ion battery.Battery Input Voltage (BAT IN): 2.5V~4.2V.Programmable low power alert interrupt threshold.Wide input voltage, compatible with 3.3V and 5V controllers.No charge-discharge relearning process, no offset accumulation errors, plug and play.Maxim's patented algorithm, accurate voltage and remaining power readings of lithium battery.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. You will find it a great help to estimate the battery life by learning the power consumption of the system with this module. When the battery power falls below specified threshold, the ALR pin generates a falling pulse to trigger the external interrupt of the controller. The module also features as a low battery power alert interrupt function. Plug and play to accurately measure the voltage and remaining power of the battery. The Gravity 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. We can only roughly judge whether the battery is full or almost empty according to its voltage. However, The remaining power and voltage of the lithium battery are highly nonlinear. 3.7V lithium batteries are commonly used in many projects.
