This document is an effort to give the understanding about stimulus response model (Software Engineering)Stimulus Response Model
What ?A system which shows the system reaction to various events is called stimulus response system.
To design the weather station using a state machine model we first need to identify the stimuli’s following table describes the stimuli for weather station
Object WeatherStation
Stimuli DescriptionreportWeather This stimulus get the summery of data from data that have been archivedCalibrate (Instruments) Used to check the accuracy of the data collected devices/hardware equipmentsStartup(Instruments) Change the state of instruments in to active stateShutdown(Instruments) Change the state of instruments in to inactive state
ReportWeather
Algorithm
when reportweather function event/trigger fired then
1. Report weather contact with weather statation process Collect().2. The collect will get the data from devices or from data archiving module3. the summarize function then summarize the collected data and send.
Report weather

Calibrate
Algorithm
This function takes the argument of device and then check the accuracy of device Active / inactive using calibrate function
Start up
