This service consists of a single characteristic, called Sensors, which displays a list of detected sensors to the I2C bus.
The characteristic Sensors has a value attribute containing a one byte long unsigned int. Each bit represents a sensor, according to table below.
If the bit is
1, the corresponding sensor has been detected and is working.
Heads up! The Sensors value is set at the startup. If a sensor is connected/disconnected after the startup you need to restart the system to update the attribute value.
