Do we need the particle data logger?

Hello!

If we use the weather station as a demo in our observatory, do we need the particle data logger? or can we use the power supply battery and the raspberry pi to collect data?

You can definitely use the raspberry pi to collect data. However, the Pi is more power-hungry than the Particle. Where you are geographically located will determine the power requirements for this to work (lots of cloudy days will require a bigger battery), but at a minimum, you’ll need a 20W solar panel.

Hello, you can use this link for all the information you need for using a raspberry pi data logger: GitHub - 3d-paws/3D-PAWS-Raspberry-Pi: A python library used to run a 3D-PAWS weather station.

Like blund said, we suggest stepping up the power requirements using a 20W panel, 12v battery, and buck converter to 5v for the raspberry pi

Here is a link to a sample buck converter:
