Bioelectricity Plant Signal Detector Kit with Arduino Uno & LED

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

When you touch a plant leaf, its cells fire a tiny electrical action potential — a language plants use to respond to stress. This kit amplifies those microvolt signals more than 20,000 times using dual LM358 op-amps and a 16-bit ADS1115 ADC, then visualises the real-time waveform on a 0.96-inch OLED and timestamps every spike onto a microSD card. It turns your bedroom or school lab into a plant electrophysiology station, bridging biology and embedded systems in a single afternoon.

What You'll Build

A portable touch‑response detector that captures, amplifies, and logs bioelectric signals from common Indian houseplants like money plant, aloe vera, or tomato. The OLED shows live voltage changes as you stroke or scratch a leaf, while the DS3231 RTC stamps each event so you can analyse patterns later. You’ll walk away with a working instrument ready for a CBSE science exhibition, B.Tech mini project, or Smart India Hackathon demo — no soldering, no lab bench power supply.

What You'll Learn

• High‑gain analog signal conditioning with LM358 op‑amps, turning microvolt sensor inputs into clean ADC‑ready voltages
• 16‑bit precision sampling using the ADS1115 module, far beyond Arduino’s built‑in 10‑bit ADC
• Timestamping and logging data to microSD with a DS3231 real‑time clock, creating a permanent record of plant activity
• Interpreting plant electrophysiology — from rapid touch‑evoked action potentials to slower stress responses

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for CBSE Class 11–12 students merging biology and electronics for interdisciplinary projects, B.Tech ECE/EEE undergraduates building signal‑acquisition mini projects, and ATL Tinkering Lab teams prototyping for Smart India Hackathon. If you want to demonstrate that plants “feel” touch with hard data, this kit gives you the complete hardware and AI‑guided build flow — no prior analog circuit design needed.

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.
