Description:
The CJMCU-219 INA219 is an I2C interface-based monitoring module designed for accurately measuring bi-directional current and power supply parameters without drift. Here's a breakdown of its features:
-
INA219 Chip: The module is built around the INA219 integrated circuit, which is a high-side current shunt and power monitor. The INA219 accurately measures both current and voltage and calculates power, allowing for precise monitoring of the electrical parameters in a circuit.
-
I2C Interface: The INA219 module communicates with microcontrollers or other devices via the I2C (Inter-Integrated Circuit) interface. This allows for easy integration with a wide range of microcontroller platforms and simplifies the communication process between the module and the host system.
-
Bi-Directional Current Monitoring: The module can measure both positive and negative currents flowing through the circuit. This bi-directional current monitoring capability is essential for applications where current flows can change direction, such as in battery charging and discharging circuits.
-
No Drift: The INA219 module is designed to minimize drift, ensuring accurate and stable measurements over time and varying operating conditions. This feature is crucial for applications requiring precise monitoring of current and power with minimal error.
-
High Accuracy: The INA219 module offers high accuracy in current and voltage measurements, typically with deviations of only a few milliamps or millivolts. This high level of accuracy makes it suitable for applications where precise monitoring is essential.
-
Wide Voltage Range: The module supports a wide input voltage range, typically from 0V to 26V DC. This wide voltage range allows for compatibility with various power sources and voltage levels commonly encountered in electronic circuits.
-
Current Shunt Resistor: The INA219 module features an onboard precision current shunt resistor, which allows for accurate measurement of current flowing through the circuit without the need for external components.
-
Power Calculation: In addition to current and voltage measurements, the module can calculate power (in watts) using the measured values of current and voltage. This feature provides valuable information about the power consumption of the connected load.
Overall, the CJMCU-219 INA219 I2C Interface Monitoring Module offers a versatile and accurate solution for monitoring current and power parameters in electronic circuits, with its bi-directional current monitoring capability, high accuracy, and stable performance without drift.
