03/12/2025 : Added V2 of Vertical mount and Sensor mount printable file
I'm currently working on a SPS30 mount to attach at the bottom of the sensor mount, also waterproof and WMO compatible
This is a solar radiation shield designed to be compatible with WMO standards and easy to print at home.
The shield consists of five fins and a top closure piece, with a 5V 3010 fan positioned on the last fin to push air towards the sensor mount.
The mount supports two sensors, in BME format like BME680 or AHT10, but also DHT ones are supported. You can design your own mount by requesting the steps in private messages.
The sensor is secured with two M2.5 hot-threaded inserts.
To secure the cable, it is advisable to screw in a PG7 watertight cable gland as shown in the figure. The piece already has a basic thread and has been field-tested to withstand all environmental conditions.
To close the assembly, you will need 4 M5*60 screws for the vertical clamp and 3 M5*100 screws to secure the top to the horizontal mount, which holds the entire assembly in place.
We recommend printing it in ASA or another UV-resistant material.
HARDWARE REQUIRED:
3010 5V Sunon fan (we suggest this brand for reliability)+
4 M5*60 screws for the clamp
3 M5*100 screws for fixing the assembly
PG7 for fixing the sensor cable
The fan is fixed with 4 M3 screws and a hex nut directly in the last fin, follow the picture design for referebce
