Buna sunt studenta la Facultatea de inginerie medicala . Anul acesta dau licenta si m am cam impotmolit la partea practică si ma gandeam ca poate ma poti ajuta. Trebuie sa fac o aplicatie care sa preia date din input mqtt si sa le duca prin telegraf la output influxdb. Iar in final sa afișează prin grafana.

I need production-ready firmware for a small, battery-powered GNSS device dedicated to personal tracking. The code must acquire precise location, fuse data from an accelerometer, gyroscope and temperature sensor, then push everything over a 4G/5G cellular link to my cloud endpoint (MQTT or HTTPS JSON; I can adapt to whichever you prefer). Low-power operation and over-the-air updates are essential because the unit should last weeks on a single charge while still supporting remote maintenance. You will handle sensor drivers, GNSS fix optimisation, adaptive sampling based on motion, fail-safe data buffering for areas with weak coverage, and a clear API so my mobile app team can parse the payloads effortlessly. I am happy to share PCB schematics and AT command references as soon as w...

Your task is the code. The work covers writing robust C/C++ /python code on the host & ask the Quectel/ Telit / Fibocom module over serial RX/TX (AT command set, po), bringing up the temperature, humidity probe and accelerometer data for periodic basis and merging all data into clean JSON or MQTT payloads with accurate GNSS timestamps.

My network of IoT sensors already publishes readings over MQTT; now I need those live values to flow straight into a polished dashboard. I want a small, well-structured stack based on Node-RED for message handling, InfluxDB for time-series storage, and Grafana for the visual layer. Scope • Configure Node-RED to subscribe to my MQTT topics, parse the payloads, and push cleaned data into InfluxDB with appropriate retention policies. • Build Grafana panels that refresh in real time, letting me spot anomalies at a glance. The layout should be clear on desktop and tablet. • Document the setup so I can add new sensor topics later without touching code, ideally by editing a single Node-RED flow and cloning existing Grafana panels. Acceptance Data from ever...

...Front-end: Craft a mobile-first web interface. The app must let drivers sign up or log in, see live charger status, and start/stop charging sessions in real time. • Back-end: Set up the server infrastructure that securely handles authentication, stores session data, and streams telemetry. • Device integration: Link the chargers to the server so the web app can read data and push control commands.

...device registered on the Tuya platform—whether it is a light, camera, thermostat, or future product—appear inside a ThingsBoard instance with full monitoring, control, analytics, and alerting capabilities. The scope breaks down into two parts. First, a secure, scalable micro-service (Docker-ready) that authenticates against Tuya Cloud API, listens for events, forwards telemetry to ThingsBoard over MQTT/REST, and relays commands back to the device in near real time. Second, a lightweight user-facing layer: you may propose a mobile, web, or hybrid front-end that simply visualises the data and executes basic commands. I am open to React Native, Flutter, Angular, or straight React—use whatever you feel delivers quickest without locking us in. Core expectations ...

I have a vibration sensor that must stream live readings through an ESP32, publish them to an MQTT broker, and finally display everything on a web-based dashboard built with React. Here is what I need from you: • Firmware for the ESP32 that reads the vibration sensor at an adjustable sampling rate, handles debouncing / filtering as needed, and publishes each payload in JSON to my MQTT topic. • A lightweight MQTT setup (either cloud or local—whichever is fastest for you to demonstrate) with clear connection instructions so I can replicate it later. • A React front-end that subscribes to the same topic and shows real-time charts, current values, and basic historical trends in a clean, responsive interface. Please keep the code modular and...
I'm looking for a tachometer to measure rotational speed from a motor's rotor using an ESP32 and TCRT5000 IR sensor. The speed data should be transmitted over MQTT to a public website. Requirements: - Use ESP32 and TCRT5000 IR sensor - Output display: MQTT over a public website - Protocol version: MQTT 3.1.1 Ideal Skills and Experience: - Experience with ESP32 and IR sensors - Proficient in MQTT and IoT projects - Familiar with data transmission and display on web platforms If you have relevant experience, please provide a detailed proposal.
I need a Kotlin-based Android application that connects to an IoT device over MQTT, stores the incoming sensor readings locally with Hive, and presents both the live stream and the historical log inside a clean, lightweight UI. Development can take place in Eclipse or any compatible IDE such as Android Studio, as long as the resulting APK installs and runs on Android 8.0+ without side-loading hassles. Core workflow • The app subscribes to a configurable MQTT topic, parses each payload, and shows the value on screen the moment it arrives. • Every message is saved into a Hive box so that reopening the app or losing connectivity never drops data. • The same screen lets users toggle between “Live” and “History” views so they can see r...

The goal is to create a lightweight IoT cloud layer dedicated to device management for a fleet of temperature sensors. My priority is not data analytics or visualization at this stage, but reliable onboarding, provisioning, remote configuration, firmware updates and fault monitoring of the devices themselves. I already have temperature sensors that publish over standard MQTT. What I need is: • A secure cloud-side service (AWS IoT Core, Azure IoT Hub, GCP IoT, or an open-source alternative—your recommendation is welcome) that can register new sensors, issue certificates/keys, and store basic metadata such as location and firmware version. • A simple web dashboard (React, Vue, or similar) to view registered sensors, push configuration changes, trigger OTA updates a...

...building a flexible software layer that can interface with a variety of connected devices and turn raw sensor data into actionable insight. The scope covers the complete stack—from device-side messaging through to a cloud-hosted back end and a lightweight web or mobile dashboard. The work begins with a short discovery session where we will finalise the target hardware, select the optimal protocol (MQTT, HTTP/REST, WebSockets, or a mix of Wi-Fi, BLE, or cellular links), and outline security requirements such as TLS, token-based auth, and OTA update strategy. From there, I need the core services coded (Python, Node.js, or other reasonable platform), a database schema designed for time-series data, and an API that cleanly exposes device states, alerts, and historical metrics....

...smart relay switch and I want to control it purely through natural voice prompts. The task is to build a lightweight ChatGPT-based agent that listens for a simple command like “turn the light on” or “switch the light off,” passes that intent to the relay, and gives an audible or textual confirmation that the action succeeded. The hardware side is already covered—I can expose the relay through HTTP, MQTT, or a similar local API—so the job centres on the software layer: • A small program (Python is fine, but I’m open) that taps into the OpenAI API, performs speech-to-text, parses intent, then fires the relay command. • Voice only: no need for a text UI, though a minimal log window for debugging would be useful. • Clear ...

I don’t have a preferred Android library either—feel free to recommend one. Because this is an initial, low-budget step, the scope focuses on a lean proof of concept: 1. Set up a lightweight WebSocket or MQTT broker that runs alongside my existing PHP hosting (or explain a simple workaround if GoDaddy blocks long-running processes). 2. Modify the delivery-boy Android code so it sends periodic coordinates through the new channel instead of hitting the PHP endpoint. 3. Show the customer app consuming that stream in real time on the order-tracking screen. 4. Provid...
