About this Gig

Need help connecting your electronics project to the internet? I will develop custom ESP32-based IoT solutions with sensor integration, WiFi connectivity, MQTT communication, and real-time data monitoring.

I can help you build smart monitoring systems, connected sensor devices, environmental monitoring projects, and prototypes for home automation or industrial applications.

My services include:

  • ESP32 WiFi configuration and connectivity
  • Temperature, humidity, and other sensor integration
  • MQTT publish and subscribe functionality
  • HTTP API integration
  • Sending sensor readings to dashboards or servers
  • Relay and actuator control
  • Troubleshooting and improving existing IoT code
  • Well-organized firmware with comments

You will receive source code and setup instructions based on your project requirements. Hardware wiring guidance can also be provided when the necessary information is available.

To get started, share your ESP32 board model, sensors or modules, connection requirements, preferred communication protocol, and details about your dashboard or server.

Please contact me before ordering projects requiring cloud subscriptions, complex mobile apps, custom server development, or production
