and also u can use the light transester sensor its a simple transestor that it base is a photo sinsor u but a voltage sorce in the input of the transistor and take the output to a buffer and then into ur pc as simple as that and a lint sorce will be the key when some body cut the light peem it will hit the alarm
and also it very chep and easy to do
or use the infrared sensor and u will find the circuit with it data sheet
