so what is jodyf1 talking about pir sensor reaching 230 volts..??
by the way what will happen if it reach up to 230v?
yes!! jodyf1 only mentions his negative points. please do appreciate ones effort and JUST suggest the blanks one has left.. every one know in which project you had to play with. even i made a project that could be used for severe spy purposes. after all, authors share their ideas. authors should mention precautions but again the person copying would be responsible not the author if he uses it in wrong way or do any illegal act. many projects include lasers which can prove to do a lot damage if directed towards eyes but children use it to play... it does not goes on the inventor if anyone is hurt by even the laser..
