Answer 1

1. A hardware code, before uploading to an embedded processor board first needs to be, option (a), verified and compiled.

2. Interoperability is required for Heterogeneous wireless communication protocols, Heterogeneous wireless communication protocols, and Different control models.

Thus option(d) is correct.

3. The function for reading humidity from DHT sensor from Arduino is, Option (d), dht (pin, DHT22).

4. Device interoperability problem is between; option (a), two devices.

5. Option (c), DHT is not an actuator
