Smart Shelf Weight Monitoring System (ESP32 + HX711 + Web Interface) Project Description: I am developing a final-year Electrical & Electronics Engineering project and need assistance building a smart weight monitoring system for a single shelf. The system will measure and track weight changes in real-time using a load cell sensor and transmit the data to a web-based interface. Hardware Requirements: ESP32 microcontroller (Wi-Fi enabled) HX711 load cell amplifier Load cell (weight sensor) Stable and accurate measurement (handle noise and drift) Software Requirements: ESP32 firmware (C/C++ / Arduino framework) Real-time data acquisition from HX711 Wi-Fi communication (HTTP or MQTT) Data transmission to a web server Web Interface: Simple dashboard (web-based)...
ESP32 and Arduino will drive every part of this project, turning ordinary lights and appliances into WiFi-enabled devices that I can switch on or off, schedule, and monitor from a custom mobile application. The core involves designing smart switches, integrating common sensors, and pushing data to the cloud through MQTT and Firebase so I get real-time status updates wherever I am. I expect clean, well-commented C++ firmware, a neat PCB layout that is ready for fabrication, and a companion app built with Blynk IoT or a comparable framework. Android and iOS support are both welcome; feel free to recommend the most efficient route. Because I plan to scale beyond a prototype, component selection, power-safe routing, and OTA update capability are important. Clear circuit dia...
...application so user can prefix the slot seeing the availability. I want a web based application which allows for user registartion where we capture face and other details and after that the user undertake some tests where IOT devices send data and which need to be correlated to user with date time. The system need a sensor IOT application also that listens to live sensor data arriving over MQTT (a raw TCP socket fallback is acceptable), stores each payload, and pushes the readings straight onto a real-time monitoring dashboard. The same backend must expose a small REST API so other systems can pull the latest value, a historical slice, or a simple health check. I prefer we use Postgresql like database so can maintain data records for 12 months easily. The data can be corelat...
...user interface (front-end). Interaction with our AI models will be handled through a pre-developed lightweight API. The front-end has push messaging capabilities, which have already been implemented using MQTT. The selected team members will be responsible for: - Customizing the Vuexy template in React to meet the specific requirements of our product. - Developing intuitive visual and graphical interfaces to effectively present the information processed by the AI models. - Integrate and consume the existing API for communication with AI models. - Ensure the correct functioning of MQTT-based push messaging. We are looking for professionals with a deep understanding of the React development process and experience creating user interfaces that visualize complex data cl...
...already have and what I expect from you: • Sensors & acquisition: I can source standard piezo or MEMS accelerometers and an RPM pickup, but I need guidance on the optimal sensor grade, mounting positions, and a compact DAQ (Raspberry Pi, ESP32, NI cDAQ, or similar—open to your recommendation) capable of simultaneous sampling. • Connectivity & protocol: Data has to leave the shop floor securely. MQTT or REST over Ethernet/Wi-Fi is acceptable; if you favour another lightweight protocol, let me know why. • Cloud/backend: A small AWS, Azure, or on-prem InfluxDB/Grafana stack is fine so long as I end up with a browser-based dashboard that shows live values, historical plots, and colour-coded alarm states. Automatic e-mail/SMS alerts when vibration exc...
...app, and the ESP32 instantly confirms that the payment succeeded before triggering the rest of my system. What matters most is rock-solid transaction verification. The device must generate or display a QR code, listen for the incoming callback from PhonePe (or poll, if that is the only option PhonePe’s API allows), parse the response, and expose the result locally (GPIO change, serial print, or MQTT publish—I’m flexible on that detail as long as it is reliable). No receipt printing or push notifications are required; I only need a clear success/failure confirmation along with the amount and transaction ID. I already have the hardware (ESP32-WROOM, 2.4-inch TFT, and internet connectivity via Wi-Fi). What I’m missing is the firmware plus the exact API inte...
...ignition status, fuel-level sensor and an output relay for safe engine cut-off. • Over-the-air firmware update support so I never have to recall a device for basic fixes or tweaks. Firmware & Protocol The device should package GPS, fuel and status data in efficient binary or JSON packets and push them to my server over GPRS at configurable intervals (default 10 s when moving, 60 s when idle). MQTT or a lightweight TCP protocol is preferred for low latency. Downlink commands must allow engine cut/restore, geofence table updates and sampling-rate changes. Server & Interface A cloud-hosted backend (Node.js, Python or PHP with MySQL/PostgreSQL) will ingest the data, persist it and expose REST/WebSocket endpoints to a responsive web dashboard and an Android/iOS ap...

...are welcome). Every inference event should be written to a log (CSV or lightweight database) with a timestamp, the detected emotion, and its confidence. When the same negative emotion (sad, angry, fearful, disgust) is observed repeatedly over a configurable window, an alert must fire—initially an on-screen banner and a console message are enough, but leave hooks so I can later plug in email or MQTT notifications. For visibility, wrap the system in a small dashboard built with Streamlit or Flask. The dashboard should: • stream the annotated video, • show the latest emotion and confidence, • display a rolling chart or table of recent detections, and • expose simple sliders or text fields to adjust alert thresholds without restarting the app. Acce...
Project Summary We need a senior developer or small senior team to build a production-grade web platform connected to ESP32-based devices via secure MQTT. This is not a simple website, not a UI-only task, and not a beginner project. We already have product direction, completed firmware, PCB work in progress, UI screens, and a detailed functional specification. We now need strong execution. What Must Be Built • Customer web application: QR flow, guest checkout, login, wallet, top-up, pay-and-start, session success, transaction history, map, support, settings, legal pages. • Business / fleet system: company wallet, vehicle management, driver/vehicle sub-accounts, assigned budgets, fleet usage, exports. • Operator dashboard: location-scoped transactions, r...

...high-speed vehicle movement. Image enhancement, motion-blur compensation, and clever data-augmentation strategies are all fair game as long as they translate into measurable accuracy gains after conversion to TensorRT or ONNX. Alongside model work, you will craft a robust video pipeline with OpenCV and Python that can pull RTSP feeds, batch or single-frame them sensibly, and expose clean JSON or MQTT outputs for the rest of our stack. Field issues do crop up, so part of the role is writing self-diagnostics and remote-update hooks to keep hundreds of Jetson boxes healthy without on-site visits. Deliverables • Trained and optimised ANPR + vehicle detection/classification models (TensorRT engine files) • Real-time Python pipeline code with clear configuration files ...
I need a set of production-ready data-processing rule chains built inside Thingsboard Professional Edition to turn raw energy meter telemetry into a clean, timestamp-aligned kWh delta that my dashboards can consume. The flow I have in mind is straightforward: incoming readings arrive through MQTT, the rule chain pulls the previous value, calculates the delta in kWh, discards spurious negatives, then writes the result back to the correct asset’s timeseries and to a daily aggregation node. Once that pipeline is solid I can build my own widgets, so your focus is strictly on the rule-chain logic, node configuration and clear documentation. I can make available: - Metric names from devices - Live overview of our Thingsboard Instance and what we want via Teams or Zoom. Delivera...

...equipment in the sense of keeping an eye on its live performance data from anywhere. The machinery is already fitted with basic IoT-ready sensors; what is missing is the cloud-to-device bridge and a clean user interface where I can watch throughput, temperature, and fault codes in real time. Here is the flow I have in mind: • Edge device pushes sensor readings via cellular data to a secure backend (MQTT or HTTPS—use what you are most comfortable with). • Backend stores, normalises, and exposes that data through an API. • A web or mobile dashboard pulls the feed and displays key performance metrics with alerts when values drift outside preset thresholds. That monitoring dashboard is the first milestone and the only compulsory feature right now. Being ab...
...model that can detect and recognise multiple faces in the same frame, then immediately tag each recognised person with a timestamp. All inference happens locally; only the processed results travel to the cloud, never the raw video. Model size, frame rate and power draw have to suit a typical Pi 4 with a standard camera module. Connectivity & data flow The Pi should expose a small, secure REST or MQTT service that pushes attendance events to the cloud and retries automatically if connectivity drops. A simple enrolment script should let me add new faces directly on the Pi or via an API call. Cloud side The frontend will live on my preferred cloud stack (a basic React or Vue single-page app is fine) and must focus on a clean Attendance Records view: searchable, filterable ...
