ESP32 Touchless Waste Disinfection Kit
Automate Waste Disinfection with ESP32-Based Touchless Mist Bin - Compoden Kit
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 agriculture, waste handling is a vector for pathogens, odour, and manual labour. This kit turns an ordinary bin into a touchless, self-disinfecting unit that pulses an ultrasonic mist at precise schedules, validates nozzle output with a pressure sensor, and records every event on a microSD card - all driven by an ESP32. It's built for the farm shed, the dairy yard, or any agri-waste point where hygiene and data matter.
What You'll Build
An autonomous waste disinfection station. The ultrasonic mist maker generates a fine fog of disinfectant at intervals you set using the DS3231 real-time clock. As each mist cycle runs, the MPX5010 pressure sensor confirms the nozzle is dispensing correctly. The ESP32 timestamps every cycle onto the MicroSD, giving you a verifiable log of sanitisation activity - no hands, no guesswork.
What You'll Learn
- PWM-based control of an ultrasonic mist transducer using ESP32's LEDC peripheral
- Reading and calibrating an analog pressure sensor to detect fluid nozzle output
- Interfacing a DS3231 RTC to schedule tasks with millisecond accuracy
- Structuring event logs on a MicroSD using SPI, with timestamped cycle confirmations

Who This Kit Is For
Designed for B.Tech (Agricultural Engineering, ECE, EEE) final-year projects, Smart India Hackathon agriculture track participants, and agritech professionals prototyping automated sanitation solutions. Also suits researchers at IITs, NITs, or VIT working on precision livestock or waste management - anyone who needs a rugged, logged disinfection node they built themselves.
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 kit to launch the AI companion, which walks you through each connection and troubleshooting step. You can also reach us on WhatsApp for direct engineer support.
Can I adjust the misting intervals after the build?
Yes. The ESP32 firmware uses the DS3231 RTC to schedule mist cycles; you can reprogram the intervals via Arduino IDE, and the AI companion shows you exactly where to change them.
Do I need to buy the plastic bin separately?
This kit provides all electronics and a prototype board for mounting. The bin itself is not included - use any standard waste bin that fits your farm shed or dairy setup.
How can I view the logged events without removing the SD card?
The base kit logs locally. If you want remote monitoring, the ESP32's Wi-Fi can be extended later (the AI companion includes a module for this) to push data to a cloud dashboard.
