I'm from a compost tech startup (Monty Compost Co.) focused on making composting more efficient for households and industrial facilities. But our tech isn’t just for composting— it’s a versatile system that can be repurposed for a wide range of applications. So, we’ve made it open source for anyone to experiment with!

One of the exciting things about our open-source compost monitoring tech is its flexibility. You can connect it to platforms like Raspberry Pi, Arduino, or other single-board computers to expand its capabilities or integrate it into your own projects.

Our system includes sensors for: * Gas composition * Temperature * Moisture levels * Air pressure

All data can be exported as CSV files for analysis. While it’s originally built for monitoring compost, the hardware and data capabilities are versatile and could be repurposed for other applications (IoT, environmental monitoring, etc.)

If you’re into data, sensors, or creative tech hacks, we’d love for you to check it out and let us know what you build!

I love it, but surely just a temp gauge for running a hot compost is nice & simple? If mine is over 45C, I'm fairly sure that means the thermophiles are present and doing their thing

I can barely get my compost more than 5C above ambient. But I think it is mainly because the compost bin isn't big enough (one of those black plastic daleks), so has too much surface area/volume. Also, it is in a very shady spot.

Shade shouldn't be a problem. In fact, a cover is good because it helps you control the sunlight and rain.

If the pile isn't heating up it's usually either bone dry or there's not enough volume. Aim for at least one cubic meter (or 3x3x3 feet).

If you have fresh grass clippings, add them - they will help a lot. A heap of grass clippings with nothing else will heat up on its own (but don't do it because it will smell).

Your cold compost is going to be fine, it will just take longer and won't cook the weed seeds. If you have more questions there's a composting subreddit: https://www.reddit.com/r/composting/

Thanks, I have done a bit of research of carbon:nitrogen etc. I think it is lack of volume. it still produces good compost, just takes longer.

Pile size is almost all that matters for how hot it gets, in my experience.
