I will create grafana dashboards for iot and sensor monitoring

I develop embedded systems and IoT prototypes using ESP32, STM32, and Arduino platforms. From firmware development and sensor integration to LVGL interfaces, wireless communication, and hardware debugging. Expertise: • ESP32 / STM32 / Arduino firmware • IoT connectivity: MQTT, Wi-Fi, BLE, ESP-NOW • LVGL interfaces and display integration • Sensor integration, debugging, and performance optimization • Functional prototypes and hardware-software integration Whether you need a new proof of concept or help improving an existing device, I can help you move your project forward.
