Measure 100V DC Safely with This Simple Circuit ⚡

⚡ **Measure up to 100V DC safely using a simple DIY circuit!**

In this video, I’ll show you how I designed a compact **Voltage Measurement Module** that can safely scale high DC voltage (up to 100V) down to a level suitable for microcontroller ADCs like STM32, Arduino, or ESP.

🔧 **What you’ll learn:**
• How a **voltage divider** works (R1 & R2)
• Converting 100V → safe ADC voltage (~3.3V)
• Adding an **RC low-pass filter** for stable readings
• How to interface this module with your microcontroller
• Practical tips for accurate voltage measurement

---

📐 **Circuit Details:**
• R1 = 330KΩ
• R2 = 10KΩ
• R3 = 1KΩ
• C1 = 0.1µF

---

⚠️ **Important:**
This module is designed for **DC voltage only** (1V–100V).
❌ Do NOT use directly with AC mains.
Always follow proper safety precautions while working with high voltage.

🚀 **Applications:**
• Battery monitoring systems
• Power supply measurement
• Embedded & IoT projects
• Industrial sensing
