All sensors and modules operate at 5V logic, matching the Uno’s I\/O voltage. You can also repurpose these components with ESP8266 or ESP32 boards using a logic level shifter if 3.3V tolerance is required. The relay module can switch loads up to 10A at 250VAC, but always check current ratings for safe operation.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eEach sensor module has clearly labeled VCC (5V), GND, and signal pins—connect them directly to the breadboard and Uno pins as shown in the included schematics. The buzzer and relay draw more current than single I\/O pins can safely source; use the breadboard’s power rails and a transistor driver where noted in the code comments. Never exceed 20mA per pin without an external driver circuit.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days.

For strictly 5V sensors, use a logic level shifter or power them from the USB 5V rail while connecting data pins through a voltage divider, as explained in the schematics.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
