MQTT Jobs
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.

WiFi Modbus Gateway for Danfoss EKC 202C
2 days left
Verified
Project Overview This project aims to develop a small WiFi gateway that connects to a Danfoss EKC 202C refrigeration controller via Modbus RTU (RS-485) and provides a local web interface. The system should allow monitoring of key controller values and limited control via a browser. The first version is a local-only solution without cloud connectivity, but the architecture must allow future expansion to cloud services. Hardware Assumptions • ESP32 or similar WiFi-enabled microcontroller • RS485 interface module for Modbus RTU communication • Connection to Danfoss EKC 202C controller (via Modbus adapter) Setup Flow • On first boot the device starts its own WiFi Access Point • User connects via smartphone or laptop • User opens configuration page at • Use...

Smart Pharma Equipment Control PCB Design
1 day left
I need a full architecture and layout for an advanced, multi-sensor PCB that will regulate heating, cooling and humidity inside a pharmaceutical machine. The board must interface with temperature, humidity and proximity sensors as standard, while leaving room for additional inputs such as light, pressure, water-level and high/low-voltage detectors. All sensing channels have to support automatic failure detection so the system can trigger the right alarm—heater, compressor, open door, over/under temperature, over/under voltage, pressure deviation—without user intervention. On the connectivity side I want both wired and wireless options: LAN, USB, CAN-Bus and RS-485 for plant integration, plus a wireless link for cloud dashboards. A capable processor with dedicated RAM and non-v...
