TF-Luna LiDAR Garage Parking Sensor Box

This is a modified version of the ResinChem Tech's garage parking sensor. He used the TF-Mini for his sensor, but I decided to try the TF-Luna since it was ~$20 cheaper. It works perfectly (I don't mind the shorter range). The wife loves it, and I can walk in front of the vehicles once they are parked. TF-Luna LiDAR Range Sensor - Waveshare Wiki

I did not print or even download his case. I made one from scratch that I can attach the TF-Luna directly to.

He has very useful videos and is a wealth of information. I'm very thankful for his build!

My modification:

1. The TF-Luna is much cheaper than the TF-Mini, but it has a shorter range. My furthest “wake-up” distance sensed in testing was about 140 inches, which is just fine for my garage. I set it to 135".
2. The TF-Luna has 6 wires; do not use or connect wires 5 or 6. Only use the first 4 wires (5v power, RX, TX, Ground). Remember, the Luna RX wire goes to ESP TX pin, and the Luna TX wire goes to the ESP RX pin (it's counter-intuitive). If you can't get it to work, you might have swapped these.
3. I didn't use a 5v “under board, jumper wire” in my setup. I just soldered the power supply right next to the LED wires. It works fine with 36 LEDs.
4. I used a threaded barrel jack instead of the standard wired jack. 
5. Note that if the garage door is open and the Luna doesn't sense anything, the parking lights flash red (backup signal) but reacts normally once it senses the vehicle. I believe this is an issue with the coding as I've seen this happen when testing the sonic parking sensor. I'm not a programmer so I'm not going to try to fix it right now.

Parts used:

1. Elegoo PLA Plus
2. (4) M3 x 5 panhead screws for securing the ElectroCookie board inside the box and securing the lid/cover.
3. (2) M2 x 4 panhead screws for mounting the TF-Luna. (laptop M2 screws might have heads that are too large) 
4. (3) 1 ¼" gold/sheetrock screws for mounting the box to the wall. (or whatever mounting screws you want)

Orcaslicer Settings:

• 0.2 layer height (0.25 first layer)
• 3 bottom layers
• 4 top layers
• 3 wall loops
• 20% infill - Cubic
• Support enabled - Tree, everywhere ("on build plate only" NOT selected)
  • might be able to get by without support, but the trees are easily removed; it really only needs support for the large hole where the TF-Luna sits.
