3. Sensors
The SensorTag is fitted with six sensors and all
sensors are chosen to be small, energy efficient
and low cost surface mount devices. The
sensors use I2C interface and are connected to
the same interface bus with separate enable
signals. To minimize current consumption all
sensors are by default disabled and they are in
sleep mode between measurements. Each
sensor can be enabled and read individually. The
SensorTag includes the following sensors:
