In real life, we often encounter some induction control device, the subject classification of the devices in the electronic circuit is composed of various kinds of sensors, the basic principle of these sensors is through the change of other types of signal after quantitative converted into a certain number of electrical physical values, so we can know, in such a situation, we are living in a lot of sensor is out of can very good implementation.

And among many sensor, photoelectric sensor is a kind of important sensor type, this is a device which is closely linked with the optical signals, but we all know that light in our nature is a very strange matter, any matter will shine, or reflected light, so the application of the photoelectric sensor is very broad, today we will look for some of the work process of photoelectric sensor detailed explanation, hope after the interpretation we can for the working process of a photoelectric sensor have a correct understanding and scientific.

Can we found is that when we pass some induction device, the device will emit some command, to control the work of the some devices, the most obvious is the induction and induction door or alarms is induction lights, these are all made of the photoelectric sensor electronic smart products. . The process of the original is to launch out light, in the process of launching, waiting near the object, and once have the object close to the light, will be certain to reflect light back, after the process in another direction of photoelectric sensor will place a receiver, when the receiver receives the reflected light, this information will be transmitted to the control function of the CPU, then the CPU can differ according to the control signal from different control command, then executing agency after receive the command will be issued a series of actions, complete the whole process of induction.

During the working process of the photoelectric sensor, we also note that some of the good quality product will have a feedback process, the significance of the work to the accuracy of signal transmission is very big, can say after the feedback, once found to have the different signal, can produce certain modification mechanism, this mechanism will amend the wrong information, and then produce the right order.
