Battery-Powered Water Level Indicator Redesign
Budget: ₹12,500 – ₹37,500 INR
I need my current water-level indicator rebuilt from the ground up so it does far more than just show a level. The new design must constantly monitor the tank, trigger automatic fill/stop routines, and run solely from a compact battery pack. I am open to whichever display technology you feel best suits the build—I mainly care that the read-out is clear, low-power, and robust enough for daily use.
Scope of work
From concept sketches to a working prototype, you will rethink the sensing method, control logic, power management, and housing. That includes choosing the ideal microcontroller, designing the PCB, writing the firmware, and packaging everything in an enclosure that can handle occasional splashes or condensation. The finished unit should be maintenance-friendly and easy for a non-technical person to install between a tank and its pump or valve.
Essential functions
• Continuous water-level monitoring with stable, repeatable readings
• Automated water control—start/stop a pump or valve at set thresholds
• Reliable operation on batteries (no mains available) with sensible power-saving
Deliverables
1. Schematic, PCB files (KiCad/Altium) and complete BOM
2. Embedded code (Arduino/ESP32-C, STM32, or similar) with annotations
3. 3D enclosure files (STEP/STL) ready for printing or injection moulding
4. A brief assembly and calibration guide
5. Video or live demo proving the prototype meets the stated functions
I will cover prototype component costs once the design is locked. If you already have experience with low-power electronics, level sensing (ultrasonic, pressure, capacitive, etc.), and automated pump control, let’s talk timeline and milestones so we can get this device into field testing quickly.
