experimental investigation of absorber positioning in a natural convection solar drying system

Data were acquired using Dallas ds18b20 temperature sensors, Bosch Moisture Sensor BME280, turbine-type anemometer and load cell capacity of 2 kg. The datalogger used was an Arduino UNO with SD memory card write/read module. The data were recorded in the Datalogger in the . CV format and later processed in the GNU Octave software. All graphics were generated in GNU Octave and gnuplot software. Data are collected at 15-minute intervals and analyzed within the day period between 10 AM and 5 PM.
