ClimBox V1.5 is an innovative scientific device designed to conduct integrated and continuous monitoring of weather and seawater quality. This device was developed through a collaboration between the Marine Science Department of Padjadjaran University, the Marine Science Department of Sultan Ageng Tirtayasa University, and QR Smart Device Pangandaran, with the aim of providing an efficient, automated, and integrated coastal environmental monitoring system. The main control system of ClimBox uses Arduino Mega as the data acquisition center from various environmental sensors with a data collection interval of one minute. All data obtained is recorded locally on an SD card and forwarded to ESP32, which functions as a data transmission module to Google Sheet via the internet.
