09130564LXN Application Field and Working Principle

09130564LXN is a pyroelectric detector, which is widely used in various temperature detection, motion detection and optical detection. It is usually used as an infrared radiation sensor in human body detection and motion control sensor application. Pyroelectric detectors are usually used to detect, monitor, and measure the intensity of thermal radiation in infrared applications. Generally, pyroelectric detectors can be divided into linear type and nonlinear type. Other than their working temperature range and sensitivity differences, they also differ in the way they detect infrared radiation. The working principle of pyroelectric detectors is based on the pyroelectric effect, which is a characteristic of some polarized materials. When the temperature of polarized materials changes, they release charges which generates the electrical voltage that the pyroelectric detector measure. For example, when the temperature of the pyroelectric detector increases, its internal electric dipole moment increases which creates an electrical field. This electrical field generates the charge separation that the pyroelectric detector measure. The charge is then usually collected and read as an electrical signal. Linear pyroelectric detectors use a two-layer pyroelectric material to detect a change in temperature. The pyroelectric material has a strong internal field which creates a strong electric dipole moment when the temperature changes, and releases charges accordingly. The electrical signal this generates is read by the pyroelectric detector. Nonlinear pyroelectric detector materials consist of two layers of pyroelectric material which are configured in reverse directions. This setup helps to detect the change in temperature and the electric dipole moment created by it more accurately. The charges released during this process are collected by the pyroelectric detector. Pyroelectric detectors have several advantages compared to other infrared detectors. They have a higher sensitivity and faster response time, meaning they can detect smaller changes in their environment faster. They are also more efficient than thermoelectric detectors, meaning much less power is required to detect a temperature change. Additionally, they are inexpensive and small in size, making them compatible with a wide range of applications. In conclusion, 09130564LXN is an efficient pyroelectric detector which is useful in various temperature detection, motion detection and optical detection applications. Its working principle is based on the pyroelectric effect, which generates an electrical signal when the polarized material’s temperature changes. The advantages of using pyroelectric detectors include their high sensitivity, fast response time, energy efficiency and small size.
