Deskripsi
INA219 Sensor Arus dan Daya DC Current and Power Sensor
Modul INA219 membantu Anda mengukur arus dan tegangan DC lewat komunikasi I2C dengan tingkat presisi 1%. Modul ini aslinya didesain oleh Adafruit sehingga sudah tersedia library dan contoh proyek Arduinonya (di website Adafruit - cari INA219 Adafruit).

Modul ini mampu melakukan high-side current sensing sehingga rangkaian yang akan diukur tidak perlu terganggu karena perubahan Ground (low side current sensing memasang resistor pengukuran di antara load dan Ground). Modul ini mampu mengukur arus hingga 3.2A dan tegangan +26VDC. Tegangan Vcc nya hanya 3 atau 5v. Modul ini juga dapat mengukur tegangan high side, sehingga cocok untuk pengukuran battery life ataupun output solar panel.

Zero CJMCU-219 module is an I2C interface with a drift, bi-directional current / power monitor integrated circuit (IC), and further expand the energy-saving electronic products TI camp. INA219 with the industry's highest accuracy and smallest size, not only to monitor the voltage drop across a shunt resistor on the sensing shunt supply voltage, while also computing power.

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, as much as possible to help customers 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.

INA219 Other important features include:

Programmable calibration register can be read in units of ampere direct current, 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, to meet the communication requirements of up to 3.4 MHz.
