Opensource 3D printed WX (meteo) station
Sensors:
- Rain counter by ?mm
- Wind direction (16 step by 22.5°)
- Wind speed (0-? m/s)
- Temperature - two internal, one optional external DS18B20 sensor
- Pressure (BMP280 sensor)
- Humidity (HTU21D sensor)
Mechanics:
- 3D printing from 14 parts (designed in OpenScad opensource tool)
- total print time about 35 hour
- need up to 400g PETG filament
- sun shield (100g) must be from white filament
- wind blades may be prited from polycarbonate into harsh conditions
- Simply removable all wind blades for
- replaceable after damage
- remove for trasportation
- One mountpount
- vertical or horizontal customizable round radius mount with binding straps
- or M6 bottom screw
- Simply bajonet removable top rain funnel
- Rigid construction with center M6 threaded rod
- Prined azimuth sign for simply direction
Electronics:
- Designed in KiCAD opensource tool
- Powered by POE (power over ethernet)
- Contactless hall efect sensors
- No wire - center PCB from top to bottom
- Electronic ESP32-POE board from Olimex
- Expand terminal with 3V3 I2C and UART
- Available WiFi, but not implemented yet
- footprint for LoRa module, but not implemented yet
Firmware:
- Based on Arduino platform
- OTA - update firmware over ethernet, with password protection
- Telnet IP access with key autentification
- CLI (command Line Interface) configuration on telnet terminal
- Timestamp from NTP server
- MQTT publish
- Propagation value to APRS, via igate
