Sensor intergration jobs
I am building an integrated volt-ampere meter that also serves as a protection and control module for a pump system. The unit must: • Measure voltage and current accurately while reacting instantly to high/low-voltage and over/under-current conditions (these three protections are the top priority). • Manage a water-level subsystem that reads three stainless-steel probes plus one flow sensor, then drives two relays—one energises the starter circuit, the other keeps the motor running. Scope of work 1. Circuit and PCB: create the full schematic around a MindMotion MM32G0001A1T (or any other MM32 in the same family so our inventory stays unchanged), layout a compact single-board solution, and specify a CC display already stocked in-house. 2. Firmware: write clean, well...

I’m building an on-premise platform that runs physics-informed digital twins on high-performance, specialized Edge AI computers already installed throughout a commercial building. The goal is simple: reduce energy use while keeping occupants comfortable, all in real time. Here is what I need from you: • A complete autonomous control loop that ingests live sensor data, runs the digital twin locally and pushes commands back to HVAC and lighting subsystems. • Digital-twin models able to deliver all three key functions: ‑ Predictive maintenance ‑ Energy consumption analysis ‑ Environmental monitoring • Code written primarily in Differential Swift. If a low-level module truly benefits from C, C++ or Python, I’m open to mixed-language solutions...
I’m looking for a skilled CAD modeller to create a custom case for one of my devices that I’ll be printing myself on an FDM machine in PLA. Port accessibility is the single most important requirement, so every button, speaker grill, charging socket and sensor area must remain fully exposed and usable once the case is fitted. Here’s what I need from you: • A clean, watertight 3D model supplied as STL (ready to slice) plus the editable source file in your preferred package (Fusion 360, SolidWorks, or similar). • Precise wall-thicknesses and tolerances that suit standard PLA prints—think 0.2 mm layer height, 0.4 mm nozzle. • Rounded edges and internal fillets that minimise print stress, with no unsupported overhangs beyond what PLA can han...

I’m building a new IP CCTV camera that must clear India’s STQC certification, and the System-on-Module is the piece I want you to own. You should be comfortable selecting or custom-designing the SoM, bringing up Linux or RTOS on it, and interfacing a global-shutter image sensor through an ISP pipeline. Secure boot is mandatory; I’ll rely on you to create a trusted boot chain, sign the firmware, and lock down update paths so the final product is field-upgradable yet tamper-proof. If you already have experience hardening U-Boot, using ARM TrustZone/OP-TEE, or similar secure enclaves, tell me up front. Because we must pass STQC, every hardware and software choice has to come with traceable documentation. Expect to collaborate with my mechanical and compliance te...

I need a compact, web-based dashboard that reads live sensor data already sitting in my MySQL database and pushes it straight to the browser as real-time tables. The same stream must be translated on the fly into the IEC-104 protocol so our State Load Dispatch Centre can ingest it without extra middleware. Core scope • Pull sensor readings from existing MySQL tables at sub-second intervals (polling or triggers—whichever keeps latency low). • Display those readings in continuously updating HTML tables; no page refreshes, so WebSockets or Server-Sent Events make sense. • Build the IEC-104 interface: map every relevant database field to the correct information object address, manage time-tagging, and handle spontaneous as well as general interrogation...

I am building a small-scale oil-handling package and need a Siemens PLC program that keeps product moving efficiently while making sure tanks never run dry. The core of the job is to write, test, and document logic that optimises flow, pulls accurate readings from our flow sensors and low-level sensor, and then drives the valves, pumps, and any other actuators that respond to those readings. Everything must tie neatly into the HMI; I’d like operators to have both a touchscreen view and a secondary PC or hard-key option so they can work comfortably from the panel or the control room. The system’s sole purpose is process optimisation, so response time and deterministic behaviour are critical. I am already committed to Siemens hardware (S7-1200 series with a basic comfort ...
I’m building an industrial-grade robotic setup and need a sharp embedded-systems mind to move the control electronics from concept to reliable hardware-in-the-loop operation. The work centres on firmware that drives motors, interprets sensor data and communicates over CAN bus or OBD-II–style diagnostics. Most of the prototyping will happen on Arduino or ESP32 boards before we freeze the design onto a custom PCB, so familiarity with Altium Designer or KiCad for schematic capture and layout is essential. Here’s how I see the collaboration flowing: • Translate high-level motion requirements into C/C++ firmware with clean, well-commented code. • Select, integrate and tune motor drivers, encoders and safety interlocks so the robot meets industrial-speed r...

I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. ...
