I have working with the passive infrared motion detector HC-SR 501. As we know there are two variable resistors which regulates the time delay(when the detector give us signal) and sensitivity, but I can not find the range of delay. Can anybody help me to find out? Thanks in advance

 

According to the first link I came across on Google, under the "adjustments" section, it can be gleaned from the broken English that the delay range is 5-300 seconds.

 

Thanks for reply, but i could not find this information.
