2PCS INA219 I2C Interface Bi-Directional DC Current/Power Monitoring Sensor Module DIY 3V-5V IIC I2C Current Power Supply Sensor SOT23 Breakout 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 products. INA219 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 power. The 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 uV. The advantage of the high precision of the product in combination with 12 resolution, can help to reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board space. The device epic of 26 bus voltage range of 0 V to +26 V. INA219 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 3.4 MHz. All features are support software programmable INA219. Using single power supply, the working voltage between + 3.0 to + 5.5 V. Package include: 2 x INA219 I2C interface current/power monitoring sensor module

• A single power supply, the operating voltage of between +3.0 to + 5.5V.
• INA219 is small size, not only to monitor the voltage drop across a shunt resistor on the sensing shunt supply voltage, while also computing power.
• Zero drift 219 INA219 module up to 128 samples can be averaged to achieve filtering in noisy environments.
• INA219 at -40C to + 1% can be achieved within the maximum error accuracy 85C temperature range, the maximum offset is 100 uV. The high-precision products combine the advantages of 12-bit resolution, to help reduce the pressure drop on the shunt resistor, thereby minimizing power loss and power consumption and save board space. The device can be sensed bus voltage range of 0 V to +26 V.
• All properties INA219 are software programmable to support.
