INA219 module is an I2C interface with a drift, bi-directional current / power monitor integrated circuit (IC), and further expand the energy-saving electronic products TI camp.
INA219 I2C Bi-directional DC Current Power Supply Sensor, Working Voltage 3~5V; Footprint: SOT23
INA219 module small size, low cost, high accuracy. It not only can monitor the voltage drop across a shunt resistor on the sensing shunt supply voltage, but also computing power.
INA219 can be achieved within the maximum error accuracy of +1% from -40° C to 85° C temperature range, the maximum offset is 100 uV. The high-precision products combine the advantages of 12-bit resolution. This module can be sensed bus voltage range is 0 V to +26 V.
Appliaction:The module is used for I2C port zero drift / bidirectional current / power monitoring sensor module. The device is available in a SOT23 package, providing a small digital current sensing servers, laptops, power supplies, battery management and automotive and telecommunications equipment, low-cost solutions.
