I will develop custom esp32 iot firmware with sensors and mqtt

I will develop custom, reliable firmware for your ESP32 or Arduino IoT project with sensors, MQTT and Home Assistant integration.

Need a smart sensor node, environmental monitor, or automated device? I will write clean, well-documented code tailored to your exact needs.

What I specialize in:

• ESP32 / Arduino (ESP8266 also supported)
• Sensors: DHT11/22, DS18B20 (Dallas OneWire), HX711 (weight), BME280, soil moisture, PIR, ultrasonic, and many others
• Communication: MQTT, WiFi, custom HTTP API
• Integrations: Home Assistant (via MQTT or ESPHome), Node-RED, custom dashboards
• Development in Arduino IDE or PlatformIO (Arduino Framework or Espressif IDF)
• Power optimization and deep sleep modes
• Over-the-air (OTA) updates
• Clean, commented source code + full documentation

I deliver production-ready firmware that is stable, secure and easy to modify.

Perfect for:

• Smart home enthusiasts
• Makers and prototype developers
• Small businesses needing custom monitoring (temperature, weight, environment, etc.)
• Agriculture, aquaponics, or industrial sensors

Message me with your project details before ordering so I can evaluate the scope.

I provide full source code and will explain everything clearly.
