Hi,I have seen your JD carefully. I am an experienced control systems engineer with a strong background in developing automated water management solutions using Raspberry Pi, Arduino, and ESP32 platforms. I specialize in creating industrial-grade control logic that integrates analog sensors, such as ultrasonic depth transducers and TDS probes, with robust power electronics for pump management. For this RO project, I will design a system that features a custom-coded interface on a color TFT touchscreen, complemented by physical emergency stops and manual overrides for maximum reliability. I have previously built integrated filtration controllers that handle auto-flush cycles, dry-run protection for pumps, and real-time water quality monitoring with high-precision calibration. I utilize CAD software to design both the electrical schematics and the internal component layout, ensuring everything fits securely within a NEMA-rated protective enclosure. My focus is on delivering a "turn-key" solution that balances a sophisticated digital UI with the ruggedness required for water-heavy environments. I can provide a full Bill of Materials (BOM) and professional wiring diagrams that make the system easy to assemble, maintain, and scale. Best Regard. Leonid Y.

Hello. I previously worked on a small industrial RO and filtration controller for a light manufacturing facility where I handled both the electronics and control logic. I selected and integrated inline TDS sensors and calibrated them against lab reference meters during commissioning. I designed the pump control circuit using relay and solid state switching with proper protection for inductive loads. I implemented automatic tank level control using ultrasonic and pressure based level sensors depending on tank geometry. I developed the firmware to manage auto and manual operation modes with safe interlocks to prevent dry running. I built a color TFT interface that displayed live sensor values and system status in a clear layout. I added physical push buttons for critical actions like pump enable and emergency stop. I implemented touchscreen menus for configuration, thresholds, and calibration routines. Here are some of my questions to clarify. ★ What type of water level sensor are you currently considering ultrasonic, pressure, or float based ★ Do you already have specific inline TDS probes in mind or should I recommend compatible models ★ What pump voltage and power rating should the controller support ★ Do you need data logging or historical trend viewing on the screen ★ Will the enclosure be installed indoors or in a semi outdoor environment Shoot me a quick message here, and let’s chat more about you and the project.

✅✅✅ Embedded Systems & Control Interface Engineer ✅✅✅ Hi there, I have experience designing embedded control systems for water treatment and industrial applications, including pump automation, sensor integration, and user-friendly HMI interfaces. I’ve implemented touchscreen and physical-button controls with real-time display of sensor data like TDS and fluid levels. My approach is to design a modular control interface that monitors tank depth and pre/post TDS sensors, drives the water pump with auto/manual modes, and presents all data on a clear color touchscreen. Hardware buttons will complement touchscreen controls for reliability, and the system will be enclosed in a protective box. A few questions: What is the desired communication protocol for the TDS meters (analog, I2C, UART)? Preferred display size/resolution? Is remote monitoring required? I am ready to start immediately.
