- [Instructor] Connecting a sensor to the Internet
requires computing and networking,
both of which are provided by the embedded system.
The connected sensor requires both the sensor
and the embedded system,
and this is the same architecture that's used for actuators.
Bringing it all together, the connected sensor consists of
an MPU, I/O interfaces, power, and optional radios.
The sensor consists of a transducer and an analog front end,
or the actuator and the digital front end.
There are two main configurations,
stand-alone connected sensors
and connected sensor arrays.
A stand-alone connected sensor consists of
a single embedded system with a single sensor,
and it's added to existing products.
Connected sensor arrays are one embedded system
with multiple sensors.
These are used in new products.
For example, in our IoT dryer,
we would use a connected sensor array.
Stand-alone connected sensors are generally used
in commercial, industrial, and infrastructure IoT
to add an overlay network to an existing product
that's too costly to replace.
Connected sensor arrays are generally used in consumer IoT
and in new business IoT products.
