So having worked out that I can make a remote for my Nikon D80 to do some timelapse photography. I started thinking of things I can do to trigger the remote, below video shows it working but you’ll need sound to hear the shutter going.
First of all check out my tutorial for making the remote as this builds on that tutorial – also saves me having to recap and explain that. You can find that here.
Ok so now you know how I’m going to trigger the camera to take pictures. So now we need the sensor, for this I’m going to use a PIR (Pyroelectric InfraRed sensor) IC that works like a switch turning on when motion is detected, the one I’m using is basically a couple of IR emitters and sensors under a Fresnel lens – word of warning make sure you get the power supply right as they tend to smoke otherwise!. It works by measuring any difference to the background temperature and infrared radiation. I’ve also added an LED to signal when the PIR is on or off.
