Please answer below MCQ and support with explanation.
1. Consider a fire detection system that is equipped with a sprinkler, to sprinkle water on detecting a flame. Which of the following tasks may not be done by the fire detection device?
a. Convert the temperature data into the appropriate format
b. Send the data Upstream to a control Tower
c. Improve the accuracy of the collected data to fine-tune immediate action
d. Act on control commands from the control Tower to activate the sprinkler
2. Among the following, what is the best way to achieve more accurate Digitization of collected sensor values ?
a. Increase the sampling rate of the analog data, and use more binary bits to represent those values.
b. Reduce the sampling rate of the analog data, but use a fixed number of binary bits to represent those values.
c. Increase the sampling rate of the analog data, and reduce the number of binary bits used to represent those values.
d. Reduce the sampling rate of the analog data, and increase the number of bits used to represent those values.
3. Which of the following actions is least likely to occur when sensor data is collected and digitized on the device?
a. The digitized data itself is sent upstream for processing
b. An indicator value is computed based on the digitized data, and sent upstream.
c. The digitized data is merged with data from other devices and then sent upstream for processing
d. A decision is taken locally, and is sent upstream.
