Fig 2G, State diagram of electronic monitor system. First boot up stage is initialization stage 310, system will boot-up and update various parameter that previously set . After initialization 310 stage proceed to usage limit stage 320 is to set water usage limit, lowest water limit able to set is 0.1 litre which is equal to 100 millitres and highest limit able to set to 1000 litres.
Assuming everything is been setup as in Fig 2B, user need to calibrate the flow sensor 101. Turn the knob 119 to anti-clockwise till display 1031 show "FFFF" and push 1032 to enter calibration mode. Turn the knob 119 to "FF1F" to calibrate flow sensor 1 and "FF2F" to calibrate flow sensor 2 and push the confirm button. The electronic monitor system 105 suitable for pulse signal, refer to manufacture manual of flow sensor. Example: Number of pulse per litre = 100 pulses, then set the number of pulse to 100.
After selecting the pulse, push the confirm button 1032 to confirm. To go back to usage limit stage 320 turn the knob 119 to anti-clockwise till display "----".
In usage limit stage 320, user require need to turn the knob 119 and select the water usage limit, after select push the button 1032 to confirm. As mention early on, the range of water usage limit from 0.1 litre to 1000 litires. In monitor usage stage 340 is to monitoring water usage will explain later on. Select alarm stage 325, turn the knob 119 to "----" push the button 1032 to set the alarm for which tap. There are 4 choices, single tap alert mode either one, both taps alert mode and no alarm alert mode, this base on theory of 'OR' gate function. The LED light 1034a and 1034b will indicate that alarm is on/off.
After setting the alarm, user can set the water usage limit in usage limit stage 320. Press the button 1032 to confirm. The system 105 will proceed to monitor usage stage 340. In this stage 340 will monitoring amount of water usage and in check alarm stage 341 is to check whether the amount of water usage is exceeding the user usage limit that was set in usage limit stage 320.
Next stage is the monitor usage stage 340, there is no detection water flowing after some time, then proceed to total usage stage 345. Total usage stage 345, will sum up total amount of water usage within the day, this feature allow user to aware about their water usage within the day. After display the total amount of water usage, the next stage will proceed to sleep stage 350. In sleep stage 350, power consumption for the electronic monitor system 105 is at low level.
In sleep stage 350, there two ways to wake up the electronic monitor system 105. First way, is the system 105 detect water flow, this action which cause by user turn on the water tap 201. Another way is through user interface, user can turn the knob 119 to select different water usage limit. Do take note, during selection of water usage limit if user using water tap it will also recording water usage embedded. User may wish to check the water usage limit, just press the button 1032 to awake the system 105 and the system 105 will display 1031 the total amount of water usage. After a day or 24 hours, the system 105 will record the total amount of water usage in memory in usage record stage 330.
In set date/time sub stage 331, assuming the system 105 is at usage limit stage 320. Turn the knob 119 till display 1032 show "FFFF" and press button 1032.
