Abstract This study focuses on thermoelectric elements (TEE) as an alternative for room temperature control. TEE are semi-conductor devices that can provide heating and cooling via a heat pump effect without direct noise emissions no refrigerant use. An efficiency evaluation of the optimal operating mode is carried out different numbers TEE, ambient temperatures, loads. The influence additional...

Unstable temperature or being outside the control of a sample will cause change in quality itself. The purpose this study was to create system on waterbath with fuzzy logic using 7 labels. Used DS18B20 sensor as sensor, processor form an UNO arduino, thermostat part safety control, and displayed 16x4 LCD. Temperature selection between 30°C-60C. Design research pre-experimental methods one type ...
