Arduino Pollen Count Estimator: Build Your Own Airborne Allergen Detector

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform a simple Arduino into a smart environmental monitor that estimates airborne pollen levels. Using a PMS5003 optical particle sensor, this kit counts particles in the 5–30µm size range — exactly where many common pollen grains fall — and shows live readings on a sharp OLED screen. It’s a hands-on way to explore air quality, seasonal allergies, and how sensor data shapes our understanding of the world around us.

What You'll Build

You’ll assemble a compact pollen count estimator that draws in air, scans it with a laser-based particle counter, and instantly displays particle concentrations on the 0.96‑inch OLED. The device clearly shows numbers for particles in the 5–30µm bin, giving a practical proxy for pollen density. Use it at home to track allergy triggers, bring it to a science exhibition, or simply watch how air changes with dust, smoke, or even a gentle breeze.

What You'll Learn

• Interfacing the PMS5003 optical particle sensor via UART with Arduino Uno
• Parsing serial data frames to extract particle counts per size bin
• Displaying real-time sensor readings on an I2C OLED screen
• Understanding particulate matter categories and the typical size range of pollen grains
