Release sensor (PIR). Here is to introduce the use of photosensitive resistors. Photomic resistance (LDR) or photoconductors are substantially made from cadmium sulfide, selenium, aluminum sulfide, thiol, thiol sulfide. Some materials have the characteristics of the rapid ring ratio of the electrical resistance at a pa……

A sort of. It is mixed with metal powder and glass uranium to print the resistor made on the substrate by screen printing. Moisture resistance, high temperature, small temperature coefficient. (Note: The following slice fixed resistors are called a patch resistor) Patch resistor is divided into the following categories……

Xin Yongcheng Optoelectronics Co., Ltd .: About product knowledge of patch resistors We often say the patch resistor (SMDRESistor) called: thick film fixed resistors (slice fixed resistors), commonly known as patch resistors. According to the production process, two types of thick film and film are divided. The thick f……

Xin Yongcheng Optoelectronics Co., Ltd .: How to choose a patch diode and a triode: a selection of a patch diode and a patch triode. There are several main problems in the patch triode application: one is the past habitual use of through holes, how to find the corresponding sheet-like triode; the second is not availabl……

Shenzhen Xinongcheng Optoelectronics Technology Co., Ltd. is a company engaged in the design and sales of photosensitizers and application products, and is committed to the production and sales of R \\u0026 D photosensitive devices. Products are widely used in security monitoring, optical sensing and touch control mark……

Signal coupled to digital intelligence integrated chip, digital intelligence integrated circuit converts the signal into a 15-bit ADC digital signal, and when the PIUR signal exceeds the selected digital threshold, there will be the same delayed REL level output, all signals are in the chip. Finished, in recent years, ……

The thermal release electrophilic infrared sensor is mainly made of a raw material having a high thermoelectric coefficient, such as lead zirconate ceramic, lithium tantaluminate, sulfate, and other one detector to install the same or two detection elements,

The conventional infrared LED lamp bead is similar to the general visible LED lamp bead in appearance, but it emits infrared light. The voltage is generally about 1.4V, and the working current is generally less than 20mA. In order to adapt to different wo
