ATL Microplastics Detection Demo
ATL Microplastics Detection Demo Kit – Make Microplastics Visible with Arduino and UV Fluorescence
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Microplastics are invisible pollutants that contaminate our water bodies. This kit turns a global environmental crisis into a tangible classroom experiment—students build a working Arduino detector that makes fluorescent particles glow under 395nm UV light and measures intensity changes after filtration. It is a direct, hands-on introduction to optical sensing and environmental monitoring.
What You'll Build
You will assemble a complete microplastics detection station. Three UV LEDs illuminate water samples in the provided jars, causing any fluorescent particles to emit visible light. An LDR (light-dependent resistor) captures the glow intensity, which is processed by the Arduino Nano and displayed on the 0.96-inch OLED screen. By comparing readings before and after simple filtration, you quantify the reduction in fluorescence—a direct analog to how real-world microplastic pollution is tracked.
What You'll Learn
- How UV fluorescence works as a detection method for micro- and nano-scale particles
- Reading analog LDR values with Arduino and mapping them to meaningful intensity numbers
- Constructing a stable optical measurement circuit using resistors and a breadboard
- Applying the scientific method: control sample vs. filtered sample comparison and data logging

Who This Kit Is For
Designed for ATL Tinkering Labs, CBSE Class 11-12 physics and environmental science projects, B.Tech 1st-year ECE/EEE demonstrations, and Smart India Hackathon water quality prototypes. It fits naturally into the curriculum for students aged 10–15 who want to see how electronics meets environmental science—no prior soldering or coding experience required.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project – accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code included with the kit to access our AI companion, which has step‑by‑step instructions specific to this project. If you still need human help, WhatsApp us – we typically answer within a few hours.
Do I need any extra equipment or tools?
No. The kit includes the Arduino Nano, all electronic components, breadboard, wires, and the water sample jars. You only need a computer with a USB port to upload the code – no soldering, no external power supply.
How do I prepare the water samples for the experiment?
Fill one jar with tap water (control), one with pond, river, or drain water, and leave the third jar empty. After measuring the raw sample’s UV fluorescence, pour it through a fine cloth or coffee filter and measure again. The drop in LDR reading demonstrates particle removal.
Can this kit detect real microplastics in drinking water?
It demonstrates the core optical principle used in research labs: UV‑excited fluorescence and intensity comparison before and after filtration. Real microplastic analysis requires a finer membrane filter, but the electronics and sensing logic you build here are identical to a professional microplastic sensor.
UV light causes microplastic particles to fluoresce in water samples — LDR measures intensity before and after filtration.
