Soldering infrared Sensor
To make the heater I used a graphics card heatsink ,I used a 8 mm drill bit to drill a hole , the infrared sensor has a small flange on the bottom this is in contact with the heatsink, if the hole is drilled to big the infrared sensor will pass straight through
Mounted on the heatsink is a wire wound resistor. This is fixed in place with some high-temperature epoxy resin and a metal spring clip which is in contact with the resistor and fixed in between the heatsink grooves.
Solder wire to the infrared sensor legs, you need 4 pieces of heat shrink tubing, after soldering the wire to each leg of the sensor slide over a piece of heat shrink tubing.
You need some sort of heatsink, I used an old graphics card which has a fan mounted on top I removed the fan. You need to drill a hole in the centre of the heatsink to the size of the infrared sensor chip this should be as tight as possible, don't make the hole to the size of the outside flange of the sensor, apply some heat resistant glue on the inside of the hole then push in the infrared sensor so the flange is sitting on top of the heatsink. Be careful not to get any glue on the sensor window, then mount the wire wound resistor to the heatsink using some heat resistant glue or make a bracket to hold the resistor in place. You need to drill two holes in the heatsink to allow you to bolt the unit to lid of the box.
Please make sure when you solder the cable to the infrared sensor that it is long enough to reach inside the box you are going to use.
