Hi there, I have carefully reviewed your remote pump automation controller requirements and can support the complete system from architecture and schematic design through PCB layout, firmware, cloud connectivity, and field documentation. With nearly five years of experience in mechatronics, embedded systems, industrial control, PCB design, Modbus/RS485, LoRa, GSM/4G, analog sensing, relay control, and IoT integration, I can develop a robust controller with automatic/manual modes, 4–20 mA inputs, secure remote monitoring, diagnostics, and OTA capability. I am comfortable starting with a small paid test task before moving into the full hardware and firmware development. Please send me a message so we can define the I/O count, control logic, and first test milestone. Best regards, Samuel tshibangu

Hi, I can develop the smart water pump controller with automatic/manual modes, Modbus RTU/RS485, 4–20 mA input, LoRa receiver, GSM/4G cloud connectivity, relay outputs, display status, and field-commissioning documentation. My approach will be to start with a small paid test task: architecture selection, I/O map, communication plan, and one basic firmware PoC. After approval, I’ll proceed with schematic, PCB, firmware, and documentation. Recommended architecture: STM32/ESP32-class MCU with RS485 transceivers, LoRa 865–868 MHz module, Quectel/SIMCom 4G module, industrial relay drivers, isolated/protected inputs, ADC front end for 4–20 mA, and LCD/LED status interface. Deliverables: * MCU/module recommendation * Full schematic * PCB design in KiCad/Altium * Relay/output driver design * Modbus RTU input/output support * LoRa receiver integration * GSM/4G cloud data flow * Auto/manual control firmware * Sensor threshold logic * Display status/diagnostics * Wiring and calibration guide * Commissioning/test documentation I’ll focus on reliable field operation, clean firmware, industrial protection, clear documentation, and full source/design-file handover after payment.

Hi, We at HardFault can handle this as a complete hardware + firmware + IoT project. Instead of relying on an individual engineer, our team brings dedicated expertise across embedded C, Modbus/RS485, LoRa 865–868 MHz, GSM/4G, industrial PCB design, relay control, and cloud connectivity, reducing the risk of delays or single-point dependency. We can design the MCU architecture, schematic/PCB, firmware, automation logic, manual override, communications, display, and commissioning documentation, with proper testing for field deployment. We’re also happy to begin with your paid test task. Would you like us to start by proposing the MCU and communication architecture?

@Webslinger01

Your spec is refreshingly complete — this is a proper industrial controller, not a toy. I've built exactly this class of hardware: multi-protocol field devices with fail-safe logic, remote connectivity, and outdoor-rated enclosures. The acceptance criteria you've listed are the right ones, and I'll design against each of them from day one. Here's what I bring to this: → I've shipped an ESP32-based air quality monitor with custom PCB, MQTT cloud reporting, and OTA updates — the same architecture your controller needs, proven in the field → I've built a Raspberry Pi HVAC controller with RS485 + MQTT dual-protocol support for remote monitoring — the Modbus integration pattern is familiar territory → Full stack capability: schematic, PCB layout in KiCad (editable, as you require), well-commented firmware, and commissioning documentation that a technician can follow without calling me → For chip selection, I'd recommend an ESP32-S3 as the core — native RS485 via transceiver, plenty of UARTs for LoRa and GSM modules, and enough processing headroom for your control logic My approach: → First, a paid test task: I'll write a small firmware module demonstrating Modbus RTU read/write over RS485 with a sensor simulator, so you can validate my code quality and communication style before we commit → Then, full schematic and PCB design, component selection for industrial-grade relays and t

@FreeLancers360

Hello, I just finished reading your brief for "Smart Water Pump Controller", and I'm genuinely excited about the chance to work on it. I don’t just want to tick the boxes here; my aim is to hand you something that genuinely goes beyond what you pictured. From your brief I can see this involves ai, automation — all areas we handle in-house. We specialise in C Programming, Electronics, Industrial Design, Microcontroller, which lines up directly with what you need. How we'd approach it: - Clarify the use-case, inputs and the exact output you expect - Build and integrate the model / automation pipeline - Evaluate accuracy and tune against real examples - Deploy with monitoring and a clear handover I also noted you don’t need back-and-forth IP terms — that’s clear, and I’ll keep the work clean and strictly on-brief. Delivering at the scale of 868 mhz is no problem for us — we're set up for volume without dropping quality. Expect smooth progress updates throughout, full respect for your specifications, and zero surprises along the way. Send over any references you have and I’ll come back with a clear plan and milestones. Best regards, FreeLancers360 Let’s connect in chat and get started — message me anytime and I’ll reply right away!

When the LoRa receiver and GSM module both try to push alerts at the same moment, the controller can miss a critical alarm. I'll add a priority queue in firmware that buffers LoRa messages and forces GSM to send only after the queue is cleared. A dual-core STM32 with built-in hardware UARTs will give enough headroom for Modbus, LoRa and GSM traffic. A common pitfall is tying the 4-20 mA loop directly to the MCU without a shunt, which can cause drift and overload the ADC. I'll add a calibrated resistor network and software scaling so the ADC sees a stable 0-1 V range regardless of sensor tolerance. My code will run on the chosen MCU and I can start right away.

@aakaashberi

Good news: your own process — a small paid test task before the full PCB — is the right way to de-risk this, and my ₹12,500 is that Phase 1. One honest safety point first: the manual override that must work "regardless of sensor state" should be a HARDWARE interlock, not software-only. I wire manual on/off to drive the relay even if the MCU hangs — software override alone can fail exactly when you need it. Same for the abnormal-reading lock-out: firmware logic plus a hardware safe state. MCU: for Modbus RTU/RS485, LoRa 865-868, GSM/4G and 4-20mA on one board I'd use an ESP32 (LoRa via SX1276, GSM via SIM7600/A7670, RS485 via MAX485, 4-20mA via ADS1115) — or STM32 for heavier industrial I/O. I'll commit once I see relay count + sensor list. Phase 1 (this bid — your test task): firmware control engine on a dev board proving auto mode (schedule + threshold logic), instant manual override, and abnormal-reading lock-out, with Modbus RTU + LoRa receive reporting to a test dashboard. Phase 2 (scoped next): full KiCad schematic + PCB, GSM/4G cloud + OTA, multi-relay board, wiring/calibration docs. All files work-for-hire, yours on payment. Quick question: how many pumps/relays and how many Modbus sensors at launch? Aakaash

@danakah

This project is suitable for utilizing my background and experience in embedded systems and industrial automation. I recently successfully implemented a wind turbine industrial automation project that is very similar to this. I can support the entire controller design process, including MCU selection, Modbus/RS485, LoRa, 4G connectivity, analog inputs, relay control, displays, and automatic/manual pump logic. As you suggested, we plan to conduct a small-scale paid test first. Once the architecture is finalized, we will proceed with schematics, PCBs, firmware, cloud communication, and documentation for field commissioning.

@lucasa229

Hello, there? I can design the complete remote pump automation controller, including the embedded hardware, PCB, firmware and cloud communication. I can build the system around a suitable industrial MCU with Modbus RTU/RS485, 4–20 mA input, LoRa 865–868 MHz, GSM/4G, relay outputs and a local display. The firmware will support automatic sequences, schedules, sensor-based conditions, manual override, alarms, diagnostics and remote configuration. I’ll create the editable KiCad or Altium schematic and PCB, with proper isolation, protection, grounding and field-ready design for the IP65 enclosure. I’ll also provide wiring, calibration, commissioning and cloud integration documentation. I’m happy to begin with the requested paid test task before moving into the full design. Thanks.
