Improvement of Ir Proximity Sensor Based on Digital Simulation Mixed Subtraction Circuit
This paper analyses the working principle of infrared proximity sensor, puts forward an efficient environmental noise suppression method for the problem that the test results are susceptible to environmental noise impact. The method is based on digital simulation mixed subtraction circuit, through t...
