Hardware Development
I am involved in both hardware and software development. I have more than 10 years of experience in this field, especially in the design and development of embedded systems and IoT (Internet of Things) devices. I enjoy challenges that require unconventional solutions, and I thrive on finding solutions that address unique problems and situations.
Professional Background
My passion for electronics and programming began in my youth, and I first encountered microcontrollers and sensors in the 1990s. Since then, I have continuously developed my knowledge and skills to use the latest technologies and tools in my work. I completed my studies at the Szigeti György Technical School, where I graduated as an electronics and IT technician.
Hardware Development
In the field of hardware development, I primarily focus on designing embedded systems. The devices I design include various IoT sensors and actuator devices that can be used in a wide range of industries. I use Autodesk Eagle and Fusion 360 software in the design process. With Eagle, I create precise and reliable circuit designs, while Fusion 360 allows me to create 3D models that aid in the production and testing of prototypes.
Projects
IoT Sensor Network: Developed a sensor network for smart homes that collects and transmits various environmental data to a central unit. Examples of developed sensors and devices:
- Temperature, humidity, air pressure
- Light intensity
- Sunshine
- Gesture sensor
- Voice control (Speech to text)
- Measurement of radioactive background radiation
- Presence sensor
- Counting passages by direction
- Electricity measurement
- Development of a custom scale with a measurement range of 200 kg
- Vibration sensor
- Opening sensor
- Soil moisture measurement
- Hourmeter
- Complex swimming pool control
- Complex multi-boiler heating control
- RFID card reader sensor, access control system
- Barcode and QR code reader
- 2 kHz sampling rate ECG development
- High-speed non-contact thermometer sensor
- Energy monitoring and control system development
Industrial Automation Tools: As part of an industrial automation project, I developed various actuator devices that automated the operation of production lines. The reliability and accuracy of the devices were crucial, so I placed great emphasis on testing and fine-tuning.
I would highlight my device that mitigates the harmful effects of network voltage increase due to the spread of solar panels, ensuring the long life of devices connected to the protected side of the network in such a way that the solar panels can also feed back into the protected network.
Embedded Systems Software Development
In addition to hardware development, I am also involved in software development to optimize and control the operation of the designed devices. My experience extends to writing embedded software, programming various microcontroller platforms, and establishing network communication for IoT devices.
Development Tools and Languages:
- Programming languages: C, C++, Python, Node.js, Javascript
- Microcontrollers: Atmega328, ESP8266 series, ESP32 series, STM32, ARM architecture
- Development environments: Arduino IDE, SublimeText, Node-red
- Communication protocols: MQTT, HTTP, Bluetooth, Zigbee, WebSocket, RS232 / RS485, I2C, SPD, I2S, IRDA
