Controlled watering system

By Tiago, in Measures, august 20,2022.

At Yoctopuce, we like raspberries. So we thought that we would have our own local production, with an automatic watering system controlled by our modules. To do so, we retrieved a raspberry bush from the garden and we planted it in a pot with sensors to monitor its health. The aim is to adjust the water dispensing based on the humidity of the soil.

Some time ago we added SSL/TLS support to our Android library. This feature allows you to use a secure communication channel between the library and the VirtualHub v2.0 (still in BETA) or the GatewayHub. Using this new feature is quite simple, but requires some tricks if you are using a Self-signed certificate on the VirtualHub.
