A fully customizable smart automatic soap dispenser designed around a Wemos D1 Mini (ESP8266), a VL53L0X ToF distance sensor, and a peristaltic pump. Unlike standard IR-based dispensers, the ToF sensor provides more stable and reliable hand detection with improved resistance to ambient light interference.

The entire enclosure is optimized for 3D printing, with a clean and minimal design suitable for bathrooms, kitchens, workshops, or maker spaces.

Features

✔ Touchless soap dispensing
✔ VL53L0X ToF sensor for accurate hand detection
✔ Peristaltic pump control for precise dosing
✔ Adjustable soap amount
✔ Wi-Fi connectivity via Wemos D1 Mini
✔ Remote configuration through a dedicated web app
✔ Settings saved in memory
✔ Compact printable enclosure
✔ Easy assembly and maintenance

The included web interface allows remote adjustment of parameters such as:

• Dispensing duration
• Sensor sensitivity
• Detection distance
• Pump behavior and timing
• System calibration

This project started as a DIY experiment and evolved into a practical smart dispenser with complete electronic integration and remote control functionality.

Perfect for makers who want a cleaner and smarter alternative to commercial dispensers.
