Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

High-speed interrogation of sensors with Bragg grating
Lahoda, Vladimír ; Řeřucha,, Šimon (referee) ; Barcík, Peter (advisor)
This diploma thesis deals with high-speed evaluation of Bragg diffraction gratings for sensory purposes. The aim of the project is to design the hardware and software of the electronic unit, which will amplify the analog signal from the photodetectors and distribute all data using a network interface. A programmable gate array is used for data collection and accumulation, which provides control and communication between a single-board computer and an analog-to-digital converter. In addition to the evaluation itself, other functions are included, such as excitation and stabilization of the optical power of the laser diode, or temperature stabilization of critical components. The proposed concept is experimentally verified on mounted printed circuit boards.

Automated Measuring System For Irrigating Plants With Iot Connectivity
Lahoda, Vladimir
This article presents a LoRa-based automated device to control irrigation in the garden based on data from sensors monitoring the environment. The device also sends all data via its private IoT LoRa network or public LoRaWAN network. The measured data are also distributed via the internet to the Thingspeak channel. This device is mounted on a PCB and its operation is backed up by its own accumulator (operation about 3-4 weeks), although permanent connection to the mains is assumed.
