Thanks Dave, Yes, the sensor has a TO-39 package, but I didn't find the IP rating on the datasheet. If it's really IP65, it's ok for an outdoor installation in the open air. I will provide for a perfect sealing of the installation hole

hello all I have the problem on how to protect the MLX90614 sensor to read the sky and make it waterproof. I read this on the Adafruit forum: https://forums.adafruit.com/viewtopic.php?t=186466 Does anyone have any ideas how to proceed without altering the readings? Thanks

Hi Miguel, in my case there were some disadvantages and some advantages. Disadvantages: 1 - more space needed to realize the project Advantages: 1 - economical having to consider the capacitors and the integrated circuit that in the area where I live are not available and on Amazon you have to buy more pieces of the same type. An HW411 voltage regulator on Amazon, 6 units cost about $ 10 and I can use them for other things. 2 - fewer problems for the installation of the heat sink on the 7805 integrated...

This eliminates the LM708 voltage regulator and heatsink. The LM2596 voltage regulator can be found on Amazon

This eliminates the LM708 voltage regulator and heatsink.

Edit Schema

Hi, my name is Claudio and I am an Italian amateur astronomer. I am building the device and I made a change to the schematic. I attach a drawing and a photo. It could be helpful for others too. Best regards
