Hi there,
I am an engineering student. I am currently doing a project which used PIR sensor (Pyroelectric infrared sensor). I do hope to ask some questions. This sensor detects body heat and produce some voltage.Somehow, the voltage
wouldn't remain 5V when it detected movement. So I would like to know how to maintain the circuit output to TTL level signal(2.4 to 5V)so i can connect it to the parallel port then to PC. I am new to this subject, so i am really desperate for help. You can reply me through
"[email protected]", mailto:[email protected] . Thanks a lot!
Regards,
Shen
