Onion Net

Your Onion Net project looks very interesting. Roughly, how much did it cost you to put together? Are you going to add a humidity sensor? Jon (talk) 09:10, 2 June 2019 (UTC)

25W solar panel and charge controller £45. Sealed lead acid battery 17Ah £17. Plastic box £10. Old mobile phone - free. The rest is based on a ESP32 which I bought a while ago and can’t remember what it cost. I may add a few more sensors in the future. Iandickinson (talk) 14:41, 2 June 2019 (UTC)
