I am practicing IOT House at Raspberry Pi.
After playing with Raspberry Pi, let's realize home electronics & home security with Remote-Hand Raspberry_pi.
It is a program that can operate MM-CP-2112A or CP2112 classic USB bridge on Linux. It operates temperature and humidity sensor AM2320 and environmental gas sensor BME680 at the same time.
