If you are one of the many people that struggle with the dreaded βBlack thumbβ affliction, there is a solution. Just place a Koubachi WiFi plant sensor in the soil next to one of your potted plants and it will gather temperature, moisture and light information that will help you keep your plant alive and thriving. Using an iOS or Android app, the Koubachi sensor will tell you when you need to water the plant, fertilize it, move it to a better lighted or cooler area, or just lovingly stroke its leaves. Ok it wonβt tell you to stroke its leavesβ¦ that would just be weird. The price to keep your plants perky doesnβt come cheap though. AtΒ β¬130.00, which is about $162.00 here in the US, this gadget is pretty expensive. Itβs up to you to decide if you think Buddy the Begonia or Frank the Ficus is worth it.
