CJMCU-219 INA219 I2C Bi-directional Current / Power Monitor Sensor
Module

Product Description

JMCU-219 INA219 I2C Bi-directional Current / Power Monitor Sensor Module CJMCU-219 module is a with I2C interface Bidirectional current  / power monitor integrated circuit (IC),  and further expand the energy-saving electronic products TI camp. INA219 with the industry's highest accuracy & smallest size, not only to monitor the voltage drop across a shunt resistor on the sensing shunt supply voltage, while also computing power. The device is available in a SOT23 package, providing a small digital current sensing servers, laptops, power supplies, battery management & automotive & telecommunications equipment, low-cost solutions. INA219 in the temperature range -40 ℃ to + 85 ℃ can achieve maximum precision error of 1% the maximum offset is 100 u V. The high-precision products combine the advantages of 12-bit resolution, as much as possible to help customers reduce the pressure drop on the shunt resistor, thereby minimizing power loss & power consumption & save board space. The device can be sensed bus voltage range of 0 V to +26 V. Feature: Programmable calibration register can be read in units of ampere direct current, & read the power in watts. Up to 128 samples can be averaged to achieve filtering in noisy environments. I2C interface has a timeout setting, not only to prevent bus lock, but also provides high-speed mode, to meet the communication requirements of up to 3.4 MHz. All properties INA219 are software programmable to support. A single power supply
