Active Infrared Sensor for Request

hello guys i am saustik sharma and today i will be talking about active insulin sensors so let's go [Music] so infrared sensors have two types active insulin sensors and passive infrared sensors and to understand these two types of sensors you need to understand what infrared rays are and also what infrared sensors are and if you don't already know about them i would suggest you to check out our previous videos on infrared trace and infrared sensors before understanding the working principle of active infrared sensors you need to understand one property of infrared rays so infrared rays have the property of reflection so if they fall on the surface of an object they will reflect off of the surface of that object so if we take light rays for an example when we look at a mirror it's basically lighter is reflecting from the surface of that mirror so the same happens with infrared rays but
