Reduce Care Noise: ESP32-S3 Logger Detects Keywords, Activates Servo
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In busy hospital wards, noise from patient calls and verbal medication announcements can overwhelm staff and disturb recovery. This kit lets you build a smart noise pollution logger that uses the ESP32-S3 and WakeNet to detect spoken patient names and dose keywords, automatically rotates a servo to open the correct compartment, and logs every event with a real‑time clock and OLED display—turning noisy routines into a quiet, automated workflow.
What You'll Build
You’ll create a compact, AI‑powered command station. When it hears, for example, “Ravi, 500mg,” the device spins the SG90 servo to expose the medication drawer, shows the dose on the 0.96‑inch OLED, stamps the event using the DS3231 RTC, and confirms with a soft buzzer. The entire system substitutes loud intercom announcements with a targeted, silent action—exactly what a noise‑sensitive care environment needs.
What You'll Learn
- Run WakeNet on an ESP32-S3 to spot custom keywords like patient name and dose in real time
- Connect an I2S MEMS microphone for crystal‑clear audio capture and drive a servo for physical actuation
- Log incidents with a DS3231 real‑time clock and display them on a 0.96‑inch OLED
- Solder resistors, capacitors, and header pins on a PCB prototype board to build a robust sensor circuit
- Implement a confirming buzzer that reduces ambient noise pollution intelligently

Who This Kit Is For
Perfect for CBSE Class 11–12 students diving into AI‑driven IoT, B.Tech ECE/EEE first‑years creating embedded systems projects, and participants of Smart India Hackathon or ATL Tinkering Labs. If you’re designing a noise‑reduction solution for hospitals, old‑age homes, or assisted‑living facilities, this kit gives you a complete blueprint to present at reviews and competitions.
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 on the box to instantly chat with the AI build companion. It’s trained on this kit’s wiring and code. WhatsApp and email support are also available from our maker team.
Can I customize the keywords for different patient names?
Yes. The companion guides you through retraining WakeNet with your own set of names and doses, so you can adapt the device to any ward or home-care setup.
Do I need prior experience with machine learning?
None. The WakeNet model is pre‑trained and the code is ready to flash. You’ll learn how to load and run an AI model on a microcontroller without any ML background.
What servo compartment arrangement is recommended?
The included servo horn and mounting guide help you build a multi‑slot medicine dispenser. You can 3D‑print an enclosure or repurpose a small box—the companion shows both options step by step.
Environmental — WakeNet detects patient name and dose keyword. ESP32-S3 rotates servo compartment and logs event with RTC.
