Abstract
Selecting the right sensor is critical because temperature is a key parameter affecting the efficiency and lifespan of generating components, such as solar panels and wind turbines. By understanding the advantages and disadvantages of each sensor through this comparison, operators can choose the sensor that best suits the system^s specific needs, in terms of accuracy, stability, and responsiveness to changes in environmental conditions. This can ultimately improve the reliability of the monitoring system, maximize the efficiency of the energy produced, and reduce the risk of component failure in hybrid power plants. This study aims to compare the performance of the DHT21 and DS18B20 temperature sensors in a hybrid power plant monitoring system that utilizes solar and wind energy sources. This process involves testing both sensors to measure the temperature in the operating environment of the plant and then comparing them with standard temperature-measuring instruments. The experimental results show that both sensors have a maximum error of 0.018% at a temperature of 45 ̊-C. The DS18B20 sensor is more reliable for applications that require high-temperature measurement stability. In contrast, the DHT21 sensor is more suitable for detecting rapid temperature changes in the environment around the hybrid power plant.
