| - | - Adafruit_BMP280_Library | + | - Place the 3D printed part number 4, push it downwards (to the left in the picture) and screw together with two M2 x10mm screws \\ {{https:// |
| - | - Adafruit_HTU21DF_Library | + | - Now it will be necessary to press the bearing. First, make a nut on a brass threaded rod about 50mm from the edge. \\ {{https://remoteqth.com/img/wiki-wx-station2-35.jpg? |
| - | - Adafruit_Unified_Sensor | + | - Then put the smaller part of the 3D printed part number 16 on it. \\ {{https://remoteqth.com/img/wiki-wx-station2-36.jpg? |
| - | - OneWire (optional if use external DS18B20 temperature sensor) | + | - You thread the bearing \\ {{https://remoteqth.com/img/wiki-wx-station2-37.jpg? |
| - | - DallasTemperature | + | - Put on the 3D printed part number 5 according to the picture \\ {{https://remoteqth.com/ |
| - | - Download firmware from [[https://github.com/ok1hra/3D-print-WX-station|GitGub]] | + | - You thread the second (larger) 3d printed part number 16 \\ {{https://remoteqth.com/ |
| - | - Select menu Tools/Board:" | + | - Screw in the brass nut \\ {{https://remoteqth.com/img/ |
| - | - Connect micro USB between ESP32-POE and PC | + | - Lightly tighten with a number 10 wrench until resistance begins to rise \\ {{https:// |
| - | - **WARNING: not connect USB cable and POE in same time!** | + | - Disassemble the entire tool, the bearing should be pressed inside the part \\ {{https:// |
| - | - Select menu Tools/Port/YOUR-CONNECTED-PORT | + | - The new bearings have considerable resistance. Over time, it will decrease during rotation. This process can be accelerated with a simple tool, with which we spin the bearing for a few minutes with a drill. |
| - | - Upload firmware | + | - We describe all magnets with north and south fields \\ {{https:// |
| - | - After firmware upload you can upload next version | + | - Field detection can be done in two ways |
| - | - password for OTA upload | + | - using the compass |
| - | - After first upload also available upload binary via web \\ {{https:// | + | - by attaching a magnet to the hall probe on the main PCB Wx of the station, the probe responds to the N pole |
| + | - We insert the rectangular magnet into the gap in the 3d printed part number 5 so that the N pole points towards the center \\ {{https:// | ||
| + | - We press the magnet so that it does not stick out \\ {{https:// | ||
| + | - Place part number 5 with bearing and pagnet on the PCB and push it downwards | ||
| + | - Place the 3D printed part number 7 and fasten with two M2 x10mm screws \\ {{https://remoteqth.com/img/wiki-wx-station2-47.jpg? | ||
| + | - Press the bearing into the 3d printed part number 9 according to the instructions in point 5 \\ {{https:// | ||
| + | - After removing the supports, insert the magnet into part 9 so that it is oriented with the North field up \\ {{https:// | ||
| + | - Place the part on the pre-drilled structure and gently push it so that the bearing fits onto the prepared cone \\ {{https:// | ||
| + | - Be very careful not to damage the hall probes at the end of the main board, fit the round PCB and insert it into the kentor in the main board. \\ {{https:// | ||
| + | - Insert a brass threaded rod with a nut on the end into the 3D printed part. \\ {{https:// | ||
| + | - Push the threaded rod through the entire weather | ||
| + | - Insulate the top end with a small amount of silicone sealant. Larger amounts could be pushed under the plate and prevent the part from turning underneath. \\ {{https:// | ||
| + | - Put on the 3D stamped part number 10 and screw on the brass nut so that the screw does not protrude from the nut. \\ {{https:// | ||
| + | - Put on the 3d printed part number 12 and insulate the joints with silicone sealant. \\ {{https:// | ||
| + | - Gently tighten the nut on the underside of the weather station. Attention, strong questioning can deform the plastic parts. \\ {{https:// | ||
| + | - Press the cylindrical neodymium magnet into the 3D printed part number 11 so that it is oriented with the South field facing outwards. \\ {{https:// | ||
| + | - Using two M2 x10mm screws, attach the cradle to the main plate and plastic bracket number 12. The screws must remain loose so that the cradle can rotate freely. The ideal situation is when, by moving the cradle in the axis of rotation, the cradle does not touch either side (the PCB or the supporting plastic part. \\ {{https:// | ||
| + | - We verify the correct function of the cradle by tilting it, when the cradle always tilts freely. \\ {{https:// | ||
| + | - Before putting on the 3D printed part number 13, we remove the strings from its inner part with the help of hot air. Strings are thin and hard to see, but they can prevent the cradle from tipping over inside. Then we screw the part to the main structure using four M3 x10mm screws. Attention, we do not tighten with force, the screws are only in conical plastic holes, without metal nuts. \\ {{https:// | ||
| + | - Place the 3D printed part number 1 in the lower part and secure it with a brass nut. \\ {{https://remoteqth.com/ | ||
| + | - Place the 3D-printed part number 8 in the rotating part, and insert it so that it does not protrude. The accuracy of the facing of 3D printed parts is given by the accuracy of printing without overshoot at the end and excessive extrusion. \\ {{https:// | ||
| + | - We screw in the stainless steel threaded rod from the opposite side until it starts to resist, which is the end of the plastic taper hole. Then we screw the stainless steel nut onto it, by screwing it along the threaded rod we balance it so that it remains | ||
| + | - Place three 3D printed anemometer vanes (part number 6). The accuracy of the facing of 3D printed parts is given by the accuracy of printing without overshoot at the end and excessive extrusion. \\ {{https://remoteqth.com/img/wiki-wx-station2-74.jpg? | ||
| + | - Before inserting the plastic binding tape into the 3D printed part number 2, bend the end of the tape twice so that it can be inserted through the hole that is bent into the washer ring. \\ {{https:// | ||
| + | - With the help of two straps, we attach the weather | ||

The control node transmitting this information is the MQTT broker. The default settings of the WX station use the **public MQTT broker of the Internet at the address remoteqth.com.** In order to avoid dependence on an Internet connection or the availability of a public MQTT broker, **we recommend that you install your own MQTT broker** on a Raspberry PI or other device in the local network. For this you can **use some of the public instructions like [[https:// |
