The implementation of the UAV hardware for water sampling, including a description of the components, is presented below.<\/p>\n

The UAV is divided into panels that house key components. Specifically, the design features the following panels: front-upper, rear-upper, front-lower, and rear-lower.<\/p>\n

\"\"<\/a><\/p>\n

The figure shows the front upper panel. The structural components present are:
\nGreen \u2013 Raspberry Pi 5 single-board computer
\nYellow \u2013 IMX219-83 stereoscopic camera
\nLilac \u2013 USB-to-UART converter
\nLight blue \u2013 JSN-SR04T ultrasonic distance sensor driver
\nRed \u2013 M9N GPS module<\/p>\n

\"\"<\/a><\/p>\n

The figure shows the rear upper panel of the UAV. The following structural components are present:
\nRed \u2013 radio communication module (radio link) operating at 412 MHz (with an antenna routed nearby)
\nYellow \u2013 winch driver
\nLilac \u2013 24V motor driver
\nLight blue \u2013 STM32F103 development board in a socket
\nOrange \u2013 24V-to-5V DC-DC step-down converter (40W) for powering a Raspberry Pi 5<\/p>\n

\"\"<\/a><\/p>\n

The figure shows the front lower panel of the UAV. The following structural components are present:
\nRed \u2013 ELRS radio control module
\nBlue \u2013 CUAVv5+ flight controller<\/p>\n

\"\"<\/a><\/p>\n

The figure shows the rear lower panel of the UAV. The following structural components are present:
\nGreen \u2013 power connectors for two 12S batteries
\nRed \u2013 ultrasonic transceiver from the JSN-SR04T module<\/p>\n

\"\"<\/a><\/p>\n

A separate photo of the power circuit for the UAV’s main components. The following structural components are highlighted:
\nRed \u2013 connectors for attaching motors
\nYellow \u2013 winch driver for the water sampler (batometer)
\nPurple \u2013 a safety switch\/sensor located at the water sampler attachment point to detect when it is secured
\nBlue \u2013 Raspberry Pi 5
\nLight blue \u2013 USB connector for connecting the Ground Control Station
\nGreen \u2013 CUAV v5+ flight controller<\/p>\n

\"\"<\/a><\/p>\n

Structural components of the water sampler:
\nYellow \u2013 a sealed dome containing a power supply unit and a radio relay.
\nRed \u2013 a solenoid actuator for opening the water sample collection container.<\/p>\n","protected":false},"excerpt":{"rendered":"
