Complete the details for water sprinkler and any device of your choice. (An Automation Device of Your Choice - Input, Process, Output)
Example - Automatic Fire Alarm System:
Input - A temperature sensor or smoke detector continuously monitors the environment for abnormal heat or smoke particles. When temperature rises above a threshold or smoke is detected, the sensor sends an electrical signal to the microcontroller.
Process - The microcontroller receives the input signal from the sensor and compares it with preset threshold values. If the values exceed safe limits, the microcontroller decides to activate the alarm and sends commands to the output devices.
Output - The buzzer sounds an alarm to alert people, and LED indicators flash. The system may also trigger water sprinklers or send notifications to emergency services.
Explanation
The chapter encourages students to choose their own automation device and identify the Input-Process-Output cycle. Students should apply the three-step automation cycle: sensors detect changes (Input), microcontroller processes and decides (Process), and output devices execute the action (Output).
Solution Steps
Input: Temperature sensor or smoke detector monitors environment and sends electrical signal to microcontroller when abnormal conditions detected
Process: Microcontroller receives signal, compares with preset threshold values, and decides whether to activate alarm
Output: Buzzer sounds alarm, LED indicators flash, system may trigger water sprinklers or notify emergency services
