Abstract

Abstract: In order to achieve a lower cost and long-distance counting of products, a photoelectric counting circuit using 1N4148 glass encapsulated diode as photoelectric sensor is designed. In this paper, a 2 kHz laser modulated light source and a second-order high pass filter circuit are used to improve the anti-interference ability of the circuit. At the same time, the semiconductor laser is used as the optical emission device, and the 1N4148 glass sealed diode is used as the optical receiving element. The experimental results show that the designed photoelectric counting circuit can count the products in different periods of time, and it verifies the feasibility of using 1N4148 as a new photoelectric sensor in ayuction with the semiconductor laser. AS semiconductor laser is cheap, the circuit has the application prospect because of its low cost and long counting distance.
