I've got a PIR sensor module here, and I'm hoping to interface it with a PICAXE.
Dippy - I hear you're the resident expert on this.
Am I right in thinking that I can just stick a gain op-amp (equivalent to 72.5dB, whatever that is) on the output? I want to feed it into a PICAXE.
If I put a high gain op-amp on the output, will I get a digital signal, or an analogue signal? I've looked at the typical circuit in the datasheet, but I think it has timing, and is more complex than I need.
Many thanks
Andrew
