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...
...including available position, current/load, temperature, voltage, movement status, and stall/overload information. Where current/load feedback is available, allow adjustable thresholds for basic contact/resistance detection and safety limiting. Servo current/load is understood to be a proxy for physical resistance rather than a precise force measurement. I am open to adding a dedicated force/load sensor if the developer recommends one. 8. Plug-and-Play Expansion The architecture should support additional identical robot arms and cameras later. Each device should have a unique identity. The intended process should be approximately: Flash Same Firmware → Power On → Automatically Discovered → Ready Adding another identical device should not require rewriting ...

...serve customers faster and with fewer stock-outs. The whole point is efficiency: when a repair order comes in, I need to know instantly whether the right panels, paints, fillers and fast-moving consumables are on hand and, if not, receive an alert before the customer even finishes the intake process. Here is how I picture it working. Every item shelf, paint cabinet and parts bin is fitted with a sensor solution—RFID, weight sensors or another technology you recommend—that feeds live counts to a cloud dashboard. When counts dip below a preset threshold, the system suggests a purchase order or flags it on a tablet that my front-desk staff already uses. Because the goal is better customer service, the interface must be simple enough for non-technical staff to see stock ...

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 an Allen-Bradley CompactLogix processor installed at my facility in Ridgefield, NJ 07657 and I need a ladder-logic program that fully automates our conveyor line system.

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. ...
...expectations • Pointing accuracy: better than 0.5° under nominal environmental conditions; 100% uptime once locked. • Communications interface: native Ethernet/IP for command, telemetry, and reporting status. • Platform: x86/Linux preferred; however, I can compile on other POSIX systems if the code is portable. Your solution should include: 1. Real-time control loop that accepts attitude sensor data (e.g., IMU, encoders) and drives two-axis galvanometers and a MEMs array. 2. Acquisition logic capable of coarse scan, fine scan, and lock-on stages, with tunable parameters. 3. Tracking algorithms that compensate for vibration, wind-shake, and slow thermal drift. 4. Diagnostic console or web GUI so I can monitor link margin, beam wander, and error ...

I’m bringing an MLX90614 infrared temperature sensor into an ESP32-based design and need a clean, ready-to-flash solution that covers three essentials: accurate temperature readings, an immediate on-screen display, and reliable data logging. The job breaks down into two parts. First, document the wiring so I can reproduce it quickly—pin map, I²C pull-ups, and power considerations for the 3 V rail. Second, supply well-commented Arduino-compatible code (ESP-IDF is fine if you prefer) that: • polls the MLX90614 at a reasonable interval • streams both object and ambient temperatures to the Serial Monitor (or an OLED/Nextion screen if you think that’s cleaner) • stores each reading with a time stamp to SPIFFS or a micro-SD card—your cal...
