	The three standard pipe parts (cap, junction and 10.5cm of straight pipe) 63mm inside diameter / 75 mm outside diameter. Assembled total heith: 16.5mm
	Cap with milled hole for lens (exterior)
	Cap with milled hole (with and without lens). We have used Kafuter K-303 glue to fix the lens because it joins the PVC of the pipe and the PMMA of the lens very well, without yellowing with solar radiation. Remember that this glue dries with UV light.

	It is necessary to join the pipe, junction and cap with PVC glue. Next, place the chassis with the electronics (you can rotate it if you notice that it may be off-centre) and use 3 screws to secure it. Make sure that it goes smoothly into the tube, which will allow the sensor to be well centred.
