Water level control system (hardware development) / Rosemizi Abd Rahim

Efficient control of water supply is important to ensure efficient distribution of water for industrial, commercial and domestic user. Sufficient level of water pressure required is achieved with the aid of pump. Unlike normal system where pump power supply control depends on the differential pressure switch, the purpose system employs level sensors. The pump will be energised it the water fall below the predetermined lower level limit. Likewise the pump stop when the water has risen to the upper limit. The system avoids unnecessary pump activation due to slight level changes, which can trigger the differential pressure switch in the normal system. Signal transmission in sensor is flexible. It can be in the form of normal cabling or wireless systems. The latter system is adopted in this work. However it requires a quite complex circuitry which include the transmitter and receiver modules.
