It emits an infrared beam and measures the reflected light, outputting an analog voltage proportional to particle concentration. This compact module integrates easily with microcontrollers, making it ideal for air quality monitoring, HVAC systems, and DIY pollution trackers.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5 V DC (VCC), 5 V (V-LED)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e20 mA max (VCC), 10 mA (ILED)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e0 – 0.5 mg\/m³ (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e0.5 – 2.5 V (cleaned air – high dust)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-10 °C to +65 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e46 × 30 × 17.6 mm (W×D×H)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/pm2-5-air-quality-monitor-kit\"\u003eIndoor air quality monitor with real‑time PM2.5 display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-forest-fire-early-warning-kit-with-arduino-uno-plus-sensor\"\u003ePortable smoke detector for early fire warning\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eAutomated ventilation control based on dust levels\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-nano-33-iot-data-logging-project-kit\"\u003eData‑logging pollution tracker with IoT dashboard\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis sensor outputs an analog signal in the 0–5 V range, so it works with any microcontroller that has an ADC accepting 5 V. Popular choices: Arduino Uno, Mega, Nano (5 V boards) directly; ESP32\/ESP8266 (3.3 V logic) require level shifting on analog input, or use a voltage divider. Raspberry Pi needs an external ADC (e.g., MCP3008). The sensor’s V‑LED pin should be driven intermittently to prolong IR LED life, but can be tied to VCC for continuous operation.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eTypical wiring: sensor pin 1 (GND) to ground, pin 2 (Vo) to Arduino A0, pin 3 (VCC) to 5V, pin 4 (V-LED) to 5V through a 150 Ω resistor, pin 5 (LED‑GND) to ground. For best accuracy, read Vo during the LED‑ON pulse (triggered by driving a digital pin to V‑LED).\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. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the GP2Y1010AU0F works directly with 5 V Arduino boards. Connect Vo to any analog pin and read the voltage. Many Arduino libraries are available for straightforward integration.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I calibrate the sensor for accurate PM2.5 readings?\u003c\/summary\u003e\u003cp\u003eThe sensor outputs a voltage linearly related to dust density. Zero‑dust voltage is typically around 0.5 V. Use a reference instrument or clean environment to establish calibration points, then map the output to µg\/m³.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I run the LED continuously?\u003c\/summary\u003e\u003cp\u003eContinuous 5 V on V‑LED will work but shortens the IR LED lifespan. The datasheet recommends a 10 ms pulse \/ 10 ms off cycle for long‑term use. Most libraries implement pulsing by connecting V‑LED to a digital pin.\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.
