The weather station

This is a little opensource project I have been working for the last few months.

The Meteo unit provide your Astronomy software with up to date data on

• Rain Rate

• Cloud cover

• Pressure

• Temperature

• Humidity

• Dew Point

• Sky Quality

• Sky Temperature

• Sky Brightness (lux)

The unit works with either an Arduino Nano, but requires a continues USB connection. Or an Arduino Nano 33 IoT which will then enable you to communicate via Wifi. Both options do require a 12v power source.

The communication between Astronomy software and the Meteo unit is based on the ASCOM Standards.

The unit gets its data from the following hardware devices.

• BME280

• TSL2591

• MLX90614

• Capacitive Rain Sensor

• Unit Housing TFA Dostmann 98.1114.02 Case with modified top for sensors.

• Modified top for sensor was created by Andy Waddington and the design is available from Thingiverse for 3D printers

Part of the Arduino code is based on the mySQM+ DIY SQM WEATHER STATION project. The code has been used with their approval and appropriate accreditation.

Below the full circuit diagram. I have a couple of PCB’s left if you would like to buy one from me. If so, please get in contact.

As for the software for this project…..

The software for this project is completely open source and can be used and abused for your own ASCOM and or Arduino projects.

But please be kind and provide appropriate accreditation as I have done in my project.
