Useless at watering plants? There’s an app for that.
The Koubachi Wi-Fi plant sensor seems to cater for quite a specific market - wealthy and inept gardeners.
The sensor measures moisture, light intensity and temperature, and uses built in Wi-Fi to transmit analysis to an iPhone or Web app to alert the user to the plants needs.
The sensor costs a huge €122 (US$153) but the makers point out that once you’ve used it for a while on one plant and established a ‘care plan’ it can be transferred to another troubled plant. If you can’t spare the Euros for the sensor you could still download the app here to get some helpful watering tips. Or you could just water your plants every now and then like a normal person.
