我们工厂的红外人体感应探头的脚数不同，功能也有所区别：### 三脚探头- **VCC**：电源正极- **GND**：电源负极- **OUT**：信号输出### 四脚探头- **VCC**：电源正极- **GND**：电源负极- **OUT**：信号输出- **EN**：使能控制（可选）### 六脚探头- **VCC*……

Q: No high level appeared when pir was testing the timing. Did pir crash? Answer: pir is not dead, it should be PIR data ready to produce high power, is forced to pull down by the MCU. You can directly supply power to the pir, use the oscilloscope to see

1. The connection between the PIR and other devices should be as short as possible. On the dual panel or multi-layer board, try not to route the cable below the……

MSL： 通常封装完的IC，胶体或Substrate PCB 在一般的环境下 会吸收湿气，造成IC在过 SMT回流焊时，发生“爆米花”(POPCORN)的状况。湿气敏感性等级(Moisture Sensitivity Level，MSL) 被用来定义 IC 在吸湿及保存期限的等级，若IC超过保存期限，则无法保证不会因吸收太多湿气而在SMT回 流焊时发生 POPCORN现象。因此对于超过保存期限的 IC 要进行烘烤。

Xinyongcheng photoelectric infrared tube DEMO board is a kind of experimental board used to demonstrate the working principle and performance of infrared tube. It uses high quality infrared tube sensor and precision electronic components, with high accura

PIR sensor Features: Low power consumption, stable technical performance, low price, etc. PIR sensor application: It is widely used in the field of electronic anti-theft, human body, animal detector. Passive Infrared (PIR) sensor definition: A

A PIR lens, also known as a Fresnel lens, is a thin sheet made from a polyolefin material. One side of its surface is smooth, and the other side is burned with concentric circles from small to large. This texture is designed by using the dry interference

Customer C: The photosensitive surface of the sample XYC-PT5E550BC-I8 anti-infrared photosensitive device you provided is on the top, right? Xin Yongcheng: Yes, C worker Customer C: But the operating voltage is 5V. I want a 3.3V

PIR (Passive infrared) sensors usually require infrared lenses to work properly. A PIR sensor is a type of sensor used to detect a human body or other heat source, which works by measuring the temperature difference between the target object and it

在智能家居领域，雷达感应和人体感应是两种常见的技术，它们都可以用于实现自动化控制和智能监测。然而，对于哪种技术更好，却因人而异。下面我们将从几个方面对雷达感应和人体感应进行比较，以便帮助您做出更好的选择。 感应范围 雷达感应的感应范围相对较广，可以覆盖到数米至数十米的距离。而人体感应的感应范……

问：红外器件焊接测试，烙铁超过2秒，塑料支架就烫化了？器件是能过smt的吧？答：1，器件是能过smt的， 2，烙铁焊的时候注意，不要烫到塑料，可以焊接在焊盘的那个引脚上面。 3，或者用加热台加热焊接。 回流焊接 Reflow Soldering ● 回流焊次数不可以超过一次，否则 ALS 可能……
