1. Types of light sensors
1. Ambient light sensor XJC-S05-T New Jingcheng Sensor 503 Series HubaControl Fuba WTAL121-N30LMWoosen WSPSS15B20GTWang Sensor Jude Life CS20D, such as the sensor on the mobile phone In mobile applications such as laptops, the power consumption of the display reaches 30% of the total battery power, and the ambient light sensor can extend the working time of the battery to the greatest extent. Together, the ambient light sensor helps the display to supply soft pictures. When the ambient brightness is high, the LCD with the ambient light sensor will actively adjust to high brightness. When the external environment is dark, the display will adjust to low brightness for active brightness adjustment. Ambient light sensors require an infrared cut-off film to be posted on the chip, or even a drawing of the IR-cut film directly on the silicon chip.
2. Infrared light sensors should use a chargeable thermopile and a bromoiodide (KRS-5) window to sense wavelengths from 580 to 40000 nm. The sensor enables students to measure a range of phenomena, including infrared radiation from the palm of the hand.
3. The ultraviolet sensor should use a filter to measure the ultraviolet band (315)nm-400 nm). In addition to filters, sensors are also capable of sensing visible light together. The sensor consists of a UV filter, collimator, and sensor handle.
2. Classification of optical sensors
1. Optical sensors mainly include optical picture sensors, transmission optical sensors, optical mouse sensors, reflective optical sensors, etc.
2. The picture sensor is mainly used for the overall measurement of the picture. It is able to collect a general picture of the entire object into the sensing device, allowing one to accurately understand the general image of the object.
3. Reflective optical sensors are mainly used for long-distance measurement, such as measuring the distance between the earth and the moon, which requires reflective optical sensors.
What are the optical sensors? What are the categories? Optical sensors are a very useful optical sensor that converts light energy into electrical signals. It is also widely used for backlight intensity conditioning of automotive dashboards. I am confident that in the future, the types of optical sensors will become more and more diverse!

The main thing about Turck's inductive sensors
1. Attenuation of detection distance. The slip warp is made of iron, which is suitable for inductive sensor detection; The scale of the measured part of the slippery warp is slightly smaller than the scale of the standard test object, so there will be a certain attenuation.
2. On-site anti-disturbance ...

Classification of electrical strain gauges – Turck
Resistance strain gauge is a kind of element used to measure strain, which is made of 0.02-0.05mm diameter constantan wire or nickel-chromium wire wound into a grid (or corroded into a grid with a very thin metal foil) in two layers of insulating sheet (substrate), and is connected with tinned copper wire and strain gauge wire as a strain.
