Overview of Research Methods for Temperature Error Compensation of Sensors

Sensors are widely used in various industrial and agricultural production practices. However, due to factors such as materials and structures used in manufacturing or packaging, their output signals are easily affected by changes in environmental temperature, leading to measurement errors. Sensor temperature error compensation technology is an important means to improve measurement accuracy, which is of great significance for sensors to play a greater role in industrial production. By reviewing relevant literature in recent years, this article summarizes the commonly used hardware compensation methods for sensor error compensation, methods for controlling the working temperature of sensors, methods for optimizing peripheral circuit compensation, and software compensation. With the continuous development of sensor technology, temperature error compensation methods are also constantly innovating and improving. In the future, temperature error compensation for sensors will pay more attention to real-time, adaptive, and intelligent capabilities to meet high-precision measurement requirements in various complex environments. This article helps researchers to gain a deeper understanding of the research methods and current status of sensor temperature error compensation, and also provides some research ideas for researchers in related fields.
