About this Gig
HELLO AND WELCOME!
Modern water leak detection systems require more than a simple sensor. They demand intelligent embedded electronics capable of accurately detecting leaks, processing sensor data in real time, controlling visual indicators, integrating imaging systems, and communicating reliably with external devices. I specialize in designing custom water leak detection PCBs with embedded firmware, LED control, and camera integration for industrial, commercial, smart home, and IoT monitoring applications.
What I Will Provide:
- Custom electronic schematic design
- Professional PCB layout (KiCad, Altium Designer, or EasyEDA)
- Embedded firmware development
- Water leak sensor interface design
- LED status indicator integration
Why Choose Me?
- Expertise in embedded systems, PCB design, and IoT hardware
- Reliable firmware written in Embedded C/C++
- Optimized PCB layouts with excellent signal integrity and EMI performance
- Experience with STM32, ESP32, ARM Cortex, Arduino, and industrial electronics
- Manufacturing-ready deliverables for rapid prototyping or mass production
Message me today, and let's build a reliable, production-ready water leak detection solution for your project!!

FAQ
What types of vending machines do you support?
I design electronics for snack, beverage, coffee, retail, industrial, medicine, and custom vending machines.
Can you implement MDB communication?
Yes. I design and implement MDB interfaces for bill validators, coin acceptors, cashless payment systems, and vending peripherals.
Do you support RS232 communication?
Absolutely. I can integrate RS232 for Android controllers, POS terminals, industrial devices, and external peripherals.
Which microcontrollers do you use?
STM32, ESP32, ARM Cortex, Arduino, AVR, PIC, and other embedded platforms.
Can you integrate card readers and payment systems?
Yes. I can interface with POS terminals, NFC readers, QR payment modules, bill validators, and coin acceptors.
Can you redesign an existing vending controller?
Yes. I can troubleshoot, optimize, or redesign your current PCB and firmware.
