This is made to hold a BME680 (temperature, humidity, barometric pressure, and VOC gas sensor) & a TSL2591 (lux sensor).It mounts on top of a piece of 1/2" EMT. The angled pipe for the bme680 is made for a piece of 1" PVC once the sensor is mounted with that 1 screw to hold it in the center where it's not touching anything. The TSL2591 goes under piece of Lexan glued to the top.
I used a piece of #12 AWG wire instead of a screw. Strip about 1/2" of insulation off the end slide the sensor on & then put the insulation back on the wire & it holds it in place. Seal the 1" pipe at the end where it goes in to keep heat from migrating toward the sensor. I put a piece of masking tape over just the light sensor and painted the whole thing gloss white (Lexan & all) before mounting it on a pole.
Wire the 2 sensor together since they're using the same I2C bus & then tap them in the middle inside the mount pipe. (shhh gotta keep that on the DL)
I made the file customizable for slight variations in pipe dimensions.
