i need help with a timer that i use with a sensor. i just need to know what type of sensor it is. it is wired to the button on the timer and i use 2 reflectors to start it at point a and stop it at point b. it's the same button used to start the timer and stop it. so it's like somewhat of a switch. can anyone tell me what kind of a sensor this is and where i could find one? any help would be great.

 

please, your kindness say that is your engineering knowledge about lightsensor. if u please complain about it process, i will thank u.

 

i know nothing about sensors. i just want to know what sensor this is cause the one i have went bad and i would like to get a new one but i don't know what it is. all i know is it sends out a red light and when it hits a reflector it triggers the timer.
