'''Step 6: Blocking sunlight with PVC (optional) | '''Step 6: Blocking sunlight with PVC (optional)'' | ||
Since sunlight includes lots of infrared radiation, it may be necessary to shield your probe. A very simple way of doing this is to take length of PVC tube with a tight-fitting cap, make a hole in the cap for wires, and simply pull the tube + cap over your NIR probe like a lampshade. Making sure the phototransistor is pointing downwards also helps. | Since sunlight includes lots of infrared radiation, it may be necessary to shield your probe.
