CJMCU-219 INA219 I2C Bi-Directional DC Current Sensor حساس تيار مستمر

SKU: 208 The CJMCU-219 INA219 is a compact I2C bi-directional DC current sensor module designed for monitoring current, voltage and power on low-voltage DC buses. It uses a precision 0.1 ohm, 1% tolerance, 2W current sense resistor to provide accurate measurement of current flow in both directions, and reports current, bus voltage and power over a digital interface. 0.1 ohm, 1% tolerance, 2W current sense resistor for reliable measurement. Supports target bus voltages up to +26 V and senses bus voltages from 0 to 26 V. Measures currents up to ±3.2 A with a resolution of ±0.8 mA for fine detection of small changes in current. I2C- or SMBus-compatible digital interface for easy integration with microcontrollers and host systems that support these common serial protocols. Provides measured values for current, voltage and computed power for energy monitoring and diagnostic use. This module is suitable for applications requiring bidirectional current monitoring and compact, digital reporting of electrical parameters where the listed voltage and current ranges meet system requirements.
