Hello i am looking to hook up a PIR Sensor Module to activate a 555 timer kit that i purchased. I plan on using this PIR Sensor (http://openimpulse.com/blog/wp-cont...les/DYP-ME003_PIR_Sensor_Module_Datasheet.pdf) which outputs 3.3V on high on this kit (http://www.velleman.eu/downloads/0/illustrated/illustrated_assembly_manual_k2579.pdf) I would like to use the PIR sensor as the Switch SW1. I was wondering if that would be possible cause the PIR sensor only has a output of 3.3V or if that would work as the trigger. (The Schematics are in both links) Thanks in Advance
