Precision Current & Power Monitoring Made Easy
The TENSTAR INA226/INA231 sensor module is a high-accuracy, bidirectional current and power monitoring solution designed for makers, engineers, and hobbyists who demand reliable measurements without complexity. Built around Texas Instruments’ industry-standard INA226 and INA231 chips, this module delivers precise shunt-based current sensing, bus voltage monitoring, and power calculation — all over a simple I2C interface.
Whether you’re designing a battery management system, monitoring solar panel output, protecting DC motors, or debugging power consumption in embedded projects, this module gives you real-time insight into electrical behavior with lab-grade accuracy.
Key Features
- Bidirectional Current Sensing: Measures both charging and discharging currents — ideal for battery systems.
- High Accuracy: ±0.5% typical error (INA226) / ±0.25% (INA231) with integrated shunt resistor.
- Wide Measurement Range: Supports up to ±3.2A (configurable via shunt) and bus voltages from 0 to 26V.
- Power Calculation On-Chip: Automatically computes power (P = V × I) — no external MCU math needed.
- I2C Interface: Easy integration with Arduino, ESP32, Raspberry Pi, STM32, and more.
- Programmable Alerts: Configurable over-current, over-power, and under-voltage thresholds.
- Low Power Consumption: Ideal for battery-operated applications.
Why Choose This Module?
Unlike basic current sensors that require external amplifiers or complex calibration, the INA226/INA231 integrates a precision shunt, ADC, and calculation engine into a single chip. This means:
- No need for external op-amps or gain resistors.
- Minimal PCB footprint.
- Plug-and-play compatibility with popular development platforms.
- Long-term stability and temperature drift compensation.
At just $3.45, this module offers professional-grade performance at a fraction of the cost of standalone sensors or development kits. With over 1,683 units sold, it’s a trusted choice among the global maker community.
Perfect For:
- DIY power supplies and bench tools
- Electric vehicle (EV) and e-bike battery monitoring
- Solar charge controllers and MPPT trackers
- Robotics and motor driver current feedback
