In this video, I’ll show you how to build an Over-Voltage and Under-Voltage Protection System using the ZMPT101B Voltage Sensor Module. This project protects your appliances by cutting off the power supply when the voltage exceeds or falls below defined safe limits.

Here’s what you’ll learn:
✅ Features and specifications of the ZMPT101B module.
✅ How to use a relay to control power supply based on voltage thresholds.
✅ Real-time voltage monitoring on a 16x2 LCD Display.
✅ Step-by-step hardware assembly and coding tutorial.
✅ Testing and demonstration of the system.

Additionally, I’m using my custom ESP32 board with a Type-C connector, which I designed and had manufactured using JLCPCB’s PCB Assembly Service. Watch the video to learn more about how JLCPCB can bring your designs to life with their affordable and professional services!
