Using several Raspberry Pis to monitor CO2 levels in my house. Each Raspberry Pi has a CO2 sensor - wrote a little Python script to retrieve data from sensor and upload it to a server Which is also a Raspberry Pi.
I am also interested in your CO2 sensor. What kind of CO2 sensor?

#273Many of these kids don't have computers at home so as a reward for finishing their first project I'm making them a home console with some RPi's I have laying about and Pico8.

#275I have a pair of Pi Zero Ws set up as timelapse cameras that I keep in the garden - Cucumber vines and flowers opening is pretty interesting at 1 frame per minute I recently did a project with a pair of RPi 3b+ and cellular modems as construction cameras. I set up RetroPie on a 3b+, but it wasn't enough for the N64 games my wife and I wanted to play the 4 could change that Currently my security cameras are recorded u…
What do you use for the camera? I have some plants I'd like to monitor but the cameras I'd use always ended up dying due to the heat.

#276It outputs UART 9600 baud data (https://sensing.honeywell.com/honeywell-sensing-particulate-...).
Does anyone have a good link to some simple guides / advice on how to run such devices using a RPi?
Thanks!

What sensor did you use? All the ones I’ve seen tend to be pretty expensive

#278This is after a failed plan to use it for Android TV (my girlfriend made the mistake of picking a WebOS TV and I made the mistake of thinking it wouldn't be so bad). The old one was just a little too slow and only did full HD (honestly, it's fine, but if you have a 4k TV it feels kinda silly). Now that the pi4 has a bunch more power and can do 4K at 60Hz, there is another chance for this!
I'm also toying with the idea of using it for sensors. Battery powered air quality sensor to see along my walking route (there is a narrow, busy car passage that I'm curious about), or maybe measuring things like electricity or heater usage in realtime. Having a graph showing you when it gets used a lot might help identify some easy wins, since walking to the basement to check the meter is a little cumbersome. But those are just ideas.

#280I have several * Pie-hole and runs Nagios to collect information about things going on inside the network. * One running a PiDP-11 (pdp 11/70 emulator) as well as providing MOP service to boot my DEC terminal multiplexor (it provides the boot image when the mux comes up) * One is a stratum-1 time server using an Adafruit GPS module with PPS output. This because I got tired of both the reflection attacks and trying to…
