Product review & video
My name is Ahmad Shamshiri and I am presenting this tutorial from Canada Hi! welcome to Robjax. in this video I'm going to  introduce this HC fr 501 motion sensor to detect   motions either on LED that shows and also or on  the screen that shows it is detected based on   that you can do some action to control something  or a robotic car or arm so this is the module   it's 32 by 24 millimeter and it can work with 5  to 20 volts so underneath of this when I remove   it actually this is the actual module LHI 7 7 8  so this is the actual module that does the work   but they also put some circuitry to make it a  module ready to be used by robotics applications   so it can be used as a burglar alarm robotics  application any application that requires motion   detector covering is for reflection of infrared  so this works based on infrared and this covering   makes the reflection very active
