Data logger multichannel based on Arduino-Uno applied in thermal measurement of solar still Carocell L3000

Engineering measurement with many parameters requires data collection tools that are quite complex and expensive, one of which can be found in thermal measurement. Arduino, as one of the open-source microprocessor templates, can be engineered as a data logger that can be reliably performed. In this paper, will explain how to make and evaluate the performance of an Arduino-based data logger in measuring solar still Carocell L3000 performance tests. There are 12 measurement points taken on solar still Carocell L3000 using three units of Arduino-board and shield data logger as data storage independently. The sensors used include DS18B20 Waterproof, DHT22, and K-type Thermocouple with MAX6675 modules. The results of these experiments indicate that the 12 sensors installed on Arduino can read well and are stored in real-time on the SD card used in each data logger for 24 hours non-stop. Sensor readings the real-time data when solar still Carocell L3000 is tested. By understanding the characteristics of the sensors used and knowing the measurement needs in research, we can make our data loggers with a good performance and comparable with the commercial one.
