Three Channel AD Converter for Fluxgate Magnetometer

This bachelor thesis deals with the ESP32 integrated circuit and its possibilities. The final product is a stand-alone device collecting data from temperature, humidity, pressure and CO2 concentration sensors.

The theoretical part deals with the issue of Internet of Things, the description of ESP32 and other used components. The practical part is divided into two larger units. The first deals with the design and implementation of a test module with ESP32-D2WD integrated circuit itself (not existing module) to verify the functionality of a hardware solution. Next discusses the options and requirements for the final product, describes hardware design, implementation, software solution and product testing.

Keywords: IoT, ESP32, Wi-Fi, sensor, DAQ system, SCD30, BME680
