CJMCU-219 INA219 I2C Interface No drift Bi-directional Current / Power Monitoring Sensor Module

CJMCU-219 INA219 I2C Interface No drift Bi-directional Current / Power Monitoring Sensor Module is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC). 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.

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219 chip on this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision.

Features :

• Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per reading.
• For as many as 128 samplings averaging, in order to realize filter in the 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 supported software programmable INA219.
