Anonymous users2024-01-24It's relatively simple, go to the bookstore to buy some books that want to close the sensor, such as the book "Sensor and Application Circuit Design" published by Science and Technology Press, which can be used as a reference book to check a lot of specific models and parameters of sensors, and there are many detailed related sensor application circuit designs. It should be helpful to you, the circuit is nothing more than some light-controlled, voice-controlled, infrared and proximity switches and other sensors, plus a related CPU or other circuits as the control circuit is over, its design is not difficult.
Hello, it's possible that it's broken, or it's possible that you're standing too far away to feel it.
This is done through the principle of infrared reflection When the human hand or a certain part of the body is in the infrared region, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the blocking of the human hand or body, and are sent to the pulse solenoid valve through the signal processed by the microcomputer in the integrated circuit; >>>More
It seems to be an infrared sensor.
I didn't touch the infrared.
It depends on whether the connection of the sensor you buy is an external tooth or an internal tooth, because the connection methods of this kind of product are different, there are internal tooth connections, there are external tooth connections, most products are internal tooth connections, and the warp is inches that is 32 mm. Hope to adopt.
