ArduinoMeteo with ASCOM driver

Acquisition type: Drawing/Sketch

Description

This is a simple project for a meteorological station with the ObservinConditions ASCOM driver for communication with NINA, AllSkyEye, etc.
You can store the data in the fits headers.

The actual arduino code works with the following sensor:
  • I2C:
    • TSL2591: Luxometer for SQM reading
    • MLX90614: Infrared sky temperature for clouds

  • SPI:
    • BMP280: Ground temperature and pressure
      • MISO: Pin 12
      • MOSI: Pin 11
      • SCK: Pin 13
      • CS: Pin 10

  • Digital:
    • DHT22: Humidity (Pin 5). 10KΩ resistor between the Data pin and the VCC pin.

I also made a simple PCB. It has free I2C and digital ports for future upgrades (wind velocity sensor, rain sensor, etc).
PCB.jpgC1: 100nF ceramic condenser.
R1: 10KΩ resistor.I used JST connectors for all the sensors. ON/OFF switch can be bypassed soldering the left and middle pin.Known problems:
  • I2C_1 can't be used. The USB of the Arduino UNO block it.
  • Tracks should not have right angles.
