Hello, I can design a reliable touchless faucet system with precise motion sensing and controlled water shut-off. I will use robust IR/ToF sensing to avoid false triggers from water reflections and ambient light. Control will be handled via a low-cost MCU (ESP32/ATTiny) with clean debounce and timing logic. A solenoid valve driver stage will ensure smooth and safe water flow control. Circuit design will include protection (flyback, filtering) for long-term reliability. You will receive a clear schematic, PCB (optional), and complete BOM with easy sourcing. I will provide firmware with adjustable delay, sensitivity, and response tuning. Mechanical mounting concepts will ensure waterproofing and easy installation. Step-by-step installation and calibration guide will be included. The design will be scalable for multiple sinks with consistent performance.

Hi there! Designing a reliable touchless faucet system requires precise sensor placement, noise-free signal processing, and fail-safe valve control to avoid false triggers and ensure smooth operation. We will develop a complete electronics + mechanical solution with optimized sensing, stable control logic, and easy-to-install hardware. We also have access to in-house 3D printing, so enclosures and mounts can be prototyped and refined if required. ✅ Do you prefer IR proximity, ultrasonic, or capacitive sensing? ✅ What type of valve setup is currently used (manual tap, solenoid compatibility)? ✅ Power source preference (battery vs mains)? Portfolio: www.freelancer.com/u/rvwebfreelancing/mech We will be happy to address any questions and ensure a smooth project process. Ready when you are. Buildtrix Studio

@electronicsdone

Best Retrofit Electronics Design Expert for Smart Water-Saving Faucets! ⭐⭐⭐⭐⭐ Dear Client, This project will only succeed if the retrofit is reliable in daily use. Not just clever — reliable. Because the real challenge is not adding a sensor and valve. It is making the trigger behavior, shutoff timing, power strategy, wet-environment reliability, and installation method work together in a way that people do not find annoying or fragile. That is where I can help. For a retrofit faucet system, the first version needs to prove the right things: dependable detection, consistent actuation, practical installation, and simple control logic that can later be scaled to more units. If those fundamentals are weak, even a smart concept quickly becomes a maintenance problem. I can help define the electronics, control behavior, protection approach, and prototype direction so the first sink installation becomes a strong reference point instead of a one-off experiment. A few quick questions: 1. Are you already committed to a specific valve/actuator method? 2. Is the first installation mains-powered, battery-powered, or still open? If you message me, I can also outline the cleanest first-prototype approach so you validate reliability before expanding further. Best regards, Prat PCB Must Innovations

@Webslinger01

I developed a smart DrinkBot system where liquid dispensing was controlled automatically using sensors and timing logic, detecting user presence and controlling flow precisely. This is very similar to your faucet automation requirement. My Approach: I will design a system using an IR motion sensor near the faucet handle. When a hand is detected, a solenoid valve will open water flow. When no motion is detected, a timer will keep water running for a few seconds and then shut it off smoothly. I will include proper debounce logic to avoid false triggers and ensure reliable operation. I will also design a simple waterproof housing/bracket that can be 3D printed and positioned correctly near the faucet. Everything will be tested in my electronics lab for stability before delivery. Deliverables: • Complete wiring diagram • Component list with supplier links • Microcontroller code (ready to use & adjustable timer) • Mechanical mounting design (3D printable) • Installation & calibration guide If you plan to scale this, I can also handle fabrication and ship ready-to-install units for mass deployment.
