HW-831 INA219 Bi-Directional Current Power Supply Sensor Breakout Board I2C Interface Power Monitoring Sensor Module
Description:
The INA219 module is a bidirectional current / power monitoring integrated circuit (IC) with I2C interface, which further strengthens TI's energy-saving electronic product camp.
INA219 has the industry's highest accuracy and the smallest size. It can not only monitor the voltage drop across the shunt resistor, sense the shunt supply voltage, but also calculate the power supply. The device is packaged in SOT23 and provides a small, low-cost solution for digital current sensing in servers, laptops, power supplies, battery management, and automotive and telecommunications equipment.
The INA219 achieves a maximum error accuracy of 1% over a temperature range of -40C to + 85C, with a maximum offset of 100 uV. The high accuracy of this product combined with the advantages of 12-bit resolution can help customers minimize the voltage drop across the shunt resistor, thereby minimizing power loss and power consumption, and saving board space. The device can sense bus voltage from 0 V to +26 V.
Feature:
1. The programmable calibration register can directly read the current in amperes and the power in watts.
2. Up to 128 samples can be averaged to achieve filtering in a noisy environment.
3. The I2C interface has a timeout setting, which not only avoids the bus lock, but also provides a high-speed mode to meet the communication requirements of up to 3.4 MHz
4. All features of INA219 support software programmable.
5. A single power supply is used, and its operating voltage ranges from +3.0 to + 5.5V.
Specification:
Packing size: 80mm * 60mm * 7mm/3.15*2.36*0.28"
Package weight: 4g
Note:
1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.
Included:
1 X INA219 Module
