Abstract
The design of water level indicator as a device comprises several units such as microcontroller (programmable) unit, water sensing unit, Heat detecting unit, Alarm unit and power supply unit. The following components are also used in the design resistors, diode, transistor, capacitors, integrated circuits in the form of operation Amplifier and thermistor. The programmable alarm is a central processing unit of the system which received a rectified and stabilized voltage from the power supply unit for effective operation. The power supply unit distributes an equal voltage of about +5v dc to all the units. The sensing unit sent their signals to the alarm unit which processed the signal and sent it to the alarm unit. The programmable alarm is programmed in such a way that when the system senses an abnormality, the sensor units (water and heat) send the signal to the alarm, while the alarm issues the audible information or signal to the alarm unit. The alarm unit will detect the abnormality by raising the alarm which helps the occupants to evacuate from the environment and the resident. The sensitivity of the device ranges from 20 seconds to 25 seconds from the period when the indicator detected the abnormality. ...
