توضیحات بیشتر

Zero CJMCU-219 module is a drift with I2C interface, bi-directional current / power monitor integrated circuit (IC), and further expansion of the energy-saving electronic products TI camp. INA219 with the industry's highest accuracy and most compact size, not only to monitor the voltage drop across the shunt resistor, the sensing shunt supply voltage, while also calculating power. The device is available in a SOT23 package, available for digital current sensing small servers, laptops, power supply, battery management and automotive and telecommunications equipment, low-cost solutions.

INA219 at -40C to + 1% can be achieved within the maximum error precision 85C temperature range, the maximum offset of 100 uV. The product combines the advantages of high-precision 12-bit resolution, as much as possible to help customers reduce the voltage drop on the shunt resistor, thereby minimizing power loss and power consumption and saving board space. The device can be sensed bus voltage range of 0 V to +26 V.

INA219 Other key features include:
Programmable calibration register can be read in amps direct current unit, and 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, up to 3.4 MHz to meet the communication requirements

Support all the features of the INA219 are software programmable.
Single power supply, the operating voltage of between +3.0 to + 5.5V.
