Refer to comments on how to set a custom time.
int laser = D3;
int sensor = A0; //A0

int delayTime= 200;
int minuteMarker=0.5; //put how many minutes you want to pass before the alert gets sent here
//I want mine to go off after 30 seconds, so I put 0.5, or half of one minute
int timer= (minuteMarker*60000)/delayTime;//this variable checks when the alotted time has passed by multiplying the amount of minutes by 
//10000, the amount of miliseconds in a minute, and then dividing it by how frequently the code is looped
bool missingAlert = false;
int missingTime = 0;

void setup() {

  Serial.begin(9600);
  pinMode(laser, OUTPUT);
  pinMode(sensor, INPUT);
}
