Self Sustaining Terrarium

Help & Support Robot Parts

I stumbled across a cool product - a self sustaining terrarium: biorb.com/en-us/shop/terrariums/

Essentially, it will take readings from the enclosed environment on humidity, temperature and light and self adjust accordingly. This creates the perfect climate for tropical vegetation to exist. I love the concept and hate the aesthetic of the product, plus it carries an insane price tag! I’d like to design and craft my own with a vintage victorian feel. The tricky part here is to hide the mechanics of environmental control so that they don’t impact the overall vibe; everything needs to be small and easy for me to hide inside the terrarium.

I’m wondering how difficult it would be to do 3 things:

  1. Read temperature and adjust a heating element so that a constant temp can be maintained
  2. Read humidity and automatically cause a “spritzer” to mist when needed
  3. Discreetly wire several waterproof LED’s that will maintain a lighting pattern appropriate to the necessary light schedule

Any advice would be very helpful! Thank you!

You can find a range of sensors here: robotshop.com/en/sensors.html
Note that very few are rust-proof, so you’ll need to find ways to prevent rusting.
Temp & humidity: robotshop.com/en/temperature-sensors.html

Microcontrollers: robotshop.com/en/microcontrollers.html
LEDs: robotshop.com/en/lighting.html

There are various ways to heat the environment, ex:

This will involve some experimentation and quite a bit of programming.
You’ll also need to monitor the sensors themselves to see if they change because of the conditions.
