Zero drift CJMCU - 219 INA219 I2C interface Bi-directional current/power monitoring sensor module
 
CJMCU - 219 is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC), further expand the TI energy-saving electronic productsINA219 has the industry's highest precision and the small size, not only can monitor the pressure drop on the shunt resistor, sensing shunt power supply voltage, at the same time also can calculate the powerThe device adopts the SOT23 packaging, but for the server, notebook computer, power supply, battery management and digital electric vehicle and telecommunication equipment measuring flu provide small, low cost solution 
 
INA219-40 c to 85 c temperature range and can realize the maximum error of 1% accuracy, maximum offset of 100 uVThe advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board spaceThe device epic of 26 bus voltage range of 0 V to V
 
INA219 other important features include:
 
Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per read
For as many as 128 sampling averaging, in order to realize filter in noise environment
The I2C interface has a timeout, not only can avoid the bus lock, but also can provide high-speed mode, meet the communication requirements of up to 34 MHz
All features are support software programmable INA219
Using single power supply, the working voltage between 30 to 55 V
