The Application of the Idr Sensor

图片
1. Electronic photometry The photometer can be used to measure the brightness of people and objects, so as to help the photographer choose the appropriate exposure speed. The following is the schematic diagram of the electronic photometer. The ldr sensor  changes the intensity of light into the difference of resistance value, so that the brightness can be displayed directly by different currents flowing through the meter. Among them, R1 and R2 are used to adjust the surface calibration and W is used to control the sensitivity of the meter head. 2. Infrared thermometry The infrared light radiated by the measured object is modulated into 800Hz optical signal by a modulation disc with a filter, which is approximately sinusoidal wave. The modulated light entering into the idr sensor is converted into electrical signals and then sent to the FET amplifier for amplification. The output U0 can reflect the temperature. In order to reduce the influence of noise and temperature c...

Plastic Fresnel Lens S9008 Used in Alarm System

图片
Overview The fresnel lens is a optical element, one side is smooth, another side is by a ring a part of concentric garden composition. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens. The Fresnel plastic , simply say to be in the lens side have equi-distant tooth tattoo. Through these tooth tattoo, can achieve to specified spectrum light band tong (reflecting or refraction) role. The traditional grinding optical equipment band-pass optical filters are expensive. The Fresnel lens can greatly reduce costs. A typical example is PIR (passive infrared detector). PIR used widely in alarm. Advantages Easy to install High quanlity Factory price Specification Model Number: S9008 Overall size:22.8mm Focal length: 15.5mm Detectable distance: 8m Viewing angle: 120° Color: Transparent Material: HDPE FAQ 1.What is the payme...
