A little project to learn about raspberry pis, arduinos, and hardware sensors

tweeres04/raspberrypi

This is a little project that helped me learn how to use rasperry pis, arduinos, and temperature sensors.

Raspberry pi

The code in this repo.

• A small Remix web server for displaying the temperature history and trends
  • Includes a tiny /temperatures API endpoint for logging temperature readings from arduinos
• A tiny cron job that logs the current temperatures on the sensors connected to the raspberry pi every 5 mins
• Data is stored in an sqlite database

Arduino

Code not in this repo yet.

• I placed a few arduinos with temperature sensors in different rooms around my house
• They're loaded with a small program that sends its temperature readings through an API endpoint /temperatures on the raspberry pi
  • The temperatures are logged every 5 minutes, just like the raspberry pi temps
  • The temperatures include a source property so I know which room the temperature is coming from

raspberrypi's Issues

Different time periods

Start the chart on ds18b20 data start

Show high, low, average

Dht11 shouldn't be grey

Looks like prev entries

No initialization scripts or instructions

The scripts here assume there's an instance of the app already

Show proper timestamps when hovering previous period entries somehow

High low avg doesn't look gr8 on mobile

Maybe larger w horizontal scroll
