MQTT is a Client Server Publish/Subscribe messaging transport protocol. It is lightweight, quick and efficient, which makes it useful for the Internet of Things (IoT) devices and low-powered networks. It enables a client to publish or receive data from a broker (server) with very little overhead. As such, an MQTT Developer is essential in making sure that the MQTT based systems remain operational properly and all the IoT devices are able to maintain effective communication.

Here's some projects that our expert MQTT Developers made real:

  • Creating secure MQTT servers on VPS that allow for the transfer of data via API
  • Developing example code for the ESP32-S3 development board to send and receive data with Quality of Service (QoS)
  • Modifying python code to interact with various other applications using MQTT
  • Designing custom firmware for microcontrollers such as STM32, TI CC3200, etc. that utilize MQTT protocol
  • Providing custom solutions for low cost wireless spectrophotometers using MQTT

As you can see, our expert MQTT developers offer tailored solutions that cater to even the most complex projects. We invite you to take a look at our list of completed projects and consider hiring our team to get your system up and running. Post your project today on Freelancer.com and make sure you get the perfect team suited for developing an efficient MQTT based system.

    I have an ESP32 connected to a load cell and HX711 amplifier, and I need the complete firmware-to-mobile workflow that turns it into a working weight-measurement prototype. The microcontroller must read stable, calibrated values from the load cell, push them over Wi-Fi or Bluetooth, and display them inside a companion mobile app on both iOS and Android. On the hardware side, please handle: • HX711 calibration routine with tare and unit conversion • Continuous or on-demand weight sampling (configurable) • JSON payload transmission via MQTT or HTTP (I’m flexible on protocol) • Low-power sleep strategy so the ESP32 can run on battery For the software side, I’d like a clean, cross-platform mobile app (Flutter or React Native are fine) that: • Au...

    我准备上线一套面向居家场景的智能监测系统,希望通过视觉与物联网技术,及早发现老人或慢病人群的高危状况并推送告警。 核心需求 1. 高危动作异常 —— 同时精准识别“摔倒”与“跌倒”,第一时间触发报警。 2. 状态失能异常 —— 既要判断“长时间静止不动”,也要捕捉“无自主行为”状态,实现持续跟踪。 3. 出入与行为节律 —— 对家门进出时间、频次和时段进行建模,结合如厕频率、徘徊轨迹、家电使用等行为模式,挖掘偏离日常规律的征兆。 4. 生理体征 —— 基于微动信号提取呼吸、心率等指标,与个人基线比较后给出健康风险提示。 我期望的交付 • 场景与传感器选型报告:摄像头、毫米波雷达、惯性传感器等可行性分析。 • 算法与模型:包含数据清洗、特征工程、深度学习或传统 CV/信号处理方案,需给出训练脚本与推理 API。 • 功能性原型:可在本地或边缘端实时运行,界面展示告警信息,并通过 MQTT/HTTP 推送到后台。 • 技术文档:部署指南、接口说明、测试用例及关键性能指标(例如跌倒检测准确率、误报率等)。 理想人选 熟悉 OpenCV、PyTorch/TensorFlow 或 mmWave SDK,对人体姿态估计、时序异常检测有实战经验;能在 Linux + Docker 环境里快速迭代;对养老、康复或智慧家居项目有交付记录更佳。 请附上相关案例、模型效果或仓库链接,让我能快速评估你的解决思路和交付能力。期待与你合作,把这套居家安全“护身符”尽快落地。
