   The device monitors the current through a small test resistor between the battery and the negative cargo charger circuit. Because charging is the time of current accumulation,The charge and discharge of the battery can be indicated by a series of output pulses of a single communication pin which is measured by the Micro-Controller.It supports one or two Li ion batteries. Only an external detection resistor and a filter capacitor can provide a very small and simple scheme to monitor the activity of the battery charging . The micro controller provides a series of output pulses and a polarity signal. In this way, the system can start counting from the full charge state and estimate the remaining battery power at any time during the battery charge or discharge period.

CJMCU-750 SC16IS750 Single UART With I2C-Bus/SPI Interface For Industrial Control
 
 
 

LiPo batteries are a great way to power your projects. They're small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power and when they do it's often unexpected (and at the worst time). Don't be caught by surprise next time your board suddenly powers-down! The LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.
Features:
Fuel gauge system for single cell lithium ion batteries
Can be connected in circuit to monitor battery.

XH-M404 DC voltage regulator module digital DC voltage regulator DC XL4016E1 digital display voltage regulator 8A

Product parameters:
1, Size: length 16cm* width 1.6cm;
2, lamp bead :5mm round head fog LED, light uniform not dazzling (from bottom to top, green 6, blue 6, yellow 4, red 4);
3, Power supply: DC between 5V~12V, the board comes with a microUSB socket, you can use the corresponding mobile phone charging cable to plug in the power supply, also reserved 2 welding pad port;
 
Product introduction:
The louder the sound, the more the LED lights up from the bottom up. With the ups and downs of the sound, the LED will also jump with the music, especially when the DJ is playing.
About the signal input: the board has a microphone, can induction receive external sound source control LED light bead flashing, the disadvantage is that the sensitivity is not as good as the line input, easy to be affected by other external sound.
If need line input, this step is about audio signals (such as mobile phone or computer headphone jack is, can not connect the output of the amplifier or speaker, the signal is too strong, pick up, if at all, you need to attenuation of signal), can remove the microphone, the signal directly from the microphone, introducing if all light, is to adjust potentiometer (inverse clock lower) recommend this connection.

Description:
Heart Rate click carries Maxim's MAX30100 integrated pulse oximetry and heart-rate sensor. It's an optical sensor that derives its readings
from emitting two wavelengths of light from two LEDs - a red and an infrared one - then measuring the absorbance of pulsing blood through a
photodetector. This particular LED color combination is optimized for reading the data through the tip of one's finger. The signal is
processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS™ I2C interface. Developers of
end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much
pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses
3.3V power supply.
Key features:
Optical sensor: IR and red LED combined with photodetector
Measures absorbance of pulsing blood
I2C interface plus INT pin
3.3V power supply
Key Benefits:
Motion artefact resillence
Ambient light cancellation
Ready-to-use examples save development time
Supported in all MikroElektronika compilers
Applications
Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger.
Package Included:
1 X Heart rate click
