Perfect for our TI Cup project
This module worked flawlessly in our voltage monitoring system for the college competition. The isolation is solid and the output is very stable.

Safe and effective
The transformer isolation gives peace of mind when working with mains voltage. No noise issues detected in our ADC readings.

Reliable sensor for students
Bought five units for our university lab. They all performed consistently within the specified error margin. Great value for educational projects.

Good accuracy, clear instructions
Used this for a smart meter prototype. Calibration was straightforward. Only wish the pins were slightly longer for breadboarding.

Solid build quality
Compact design fits well in small enclosures. The soldering points are well-defined. Works great with STM32 microcontrollers.
Q: Is the module calibrated out of the box?
A: The module comes with factory calibration components. However, for high-precision competition requirements, we recommend performing a software calibration using a known reference voltage.
Q: Can this module directly interface with a 5V Arduino?
A: Yes, but please note the output is scaled to 3.3V max. You can connect it directly to Arduino analog pins, which will read values up to roughly 67% of the full scale, or use a voltage divider if you need full 5V scaling logic.
Q: What is the maximum current this sensor can handle?
A: This is a voltage detection sensor, not a current sensor. It measures potential difference. The input impedance is high, so it draws negligible current from the source being measured.
Q: Does it work with DC voltage?
A: No, this module is specifically designed with a transformer for AC voltage detection only. It will not output a correct signal for DC inputs.
Q: Are there example codes available for MSP430?
A: Yes, we provide a GitHub repository with example code for STM32, Arduino, and MSP430 specifically tailored for TI Cup competitions. Check the product manual for the link.
