When rcwl-0516 detects movement the output pin goes high for around 3 seconds then it goes back to zero please some one guide me how i can increase this time. i mean how to adjust the output timing of this module i want the output to remain high for around 30 seconds when motion is detected ...
if it is possible with the module itself then well n good other wise suggest me a passive circuit for it.
Thank you.

 

Hello,

The following page will tell you more about the module:

There is also a schematic on that page.

Thank you for this but i need the output pin to remain high for 30 seconds which is not mentioned any where on the page regarding the module i already i have done enough research on it but could'nt find any ways to do it.

 

Hello,

The page mentions that the chip is almost identical to the BIsS0001.
On the pins 3 and 4 there is a RC network that makes the output time.
On the board C2 determines the output time.
When you change the capacitor with a 10 times higher value the timing will be 10 times longer.
