INA219 I2C Bi-Directional Current & Power Monitoring Sensor

DescriptionCJMCU-219 is a module featuring a zero-drift I2C interface and a bi-directional current/power monitoring and control integrated circuit (IC), which expands the TI energy-saving electrical devices. The INA219 has the greatest precision and smallest size in the industry, and it can monitor the pressure drop on the shunt resistor while detecting the shunt power supply voltage and calculating the power. The device is packaged in SOT23, yet it provides a tiny, low-cost solution for the server, laptop computer, power supply, battery management, and digital electric car and communications equipment measurement needs.The temperature range of the INA219 is -40 C to 85 C, with a maximum inaccuracy of 1% accuracy and a maximum offset of 100 uV. The advantage of the product’s high accuracy in combination with 12 resolution is that it can aid clients as much as possible by reducing the pressure drop on the shunt resistor, hence minimizing power loss and power consumption and saving board space. The epic of the 26 bus voltage range is 0 V to 26 V.APPLICATIONMeasure high side voltage and DC current draw, great for tracking battery life or solar panels.Perfect for your solar or battery-powered UNO project.Used for I2C port zero drift / bidirectional current/power monitoring sensor module.SPECIFICATIONCommon mode voltage (Max): 26VCommon mode voltage (Min): 0VInput offset ( /-) (Max): 50, 100uVInput offset drift ( /-) (Typ): 0.1uV/CGain: 1, 0.5, 0.25, 0.125V/VGain error: 0.5, 0.3%Gain error drift ( /-) (Max): 83ppm/°CCMRR (Min): 120dBBandwidth: 5.5kHzSupply voltage (Max): 5.5VSupply voltage (Min): 3V Iq (Max): 1mADigital interface: I2C, SMBusResolution:12 BitsOperating temperature range: -40 to 125CDOCUMENTATIONArduino LibraryTutorialSHIPPING LIST1 x INA219 I2C Bi-Directional Current & Power Monitoring Sensor
