Abstract

The current analogue water meter is commonly used in most of the residential area for water usage amount reading. However, the water meter are installed in the house is a problematic such that the staff cannot take the water usage reading when there is nobody home. In addition, it has accuracy problem due to incorrect reading taken by staff. To solve this problem, this thesis presents the solar-powered digital water meter with wireless capability to provide wireless access to user water consumption A solar photovoltaic is used to provide sufficient power source to activate the function of this system. The water flow sensor detects the water consumption. An Arduino Uno microcontroller is used for processing the data and the radio frequency 433MHz module acts as data transmission medium. Rechargeable batteries are used to store the energy and power up the system during night time. To validate the system design, the prototype is tested for operations such as water meter sensor accuracy, the charging type time of the rechargeable batteries, the durability of rechargeable batteries and the bit error rate of data transmission. Test results conducted within 15 meters distance between the RF transceiver to send and receive data from micro controlled-digital water meter. As the results, the average accuracy of water meter is 1.58% that has proven the water flow sensor accuracy is within the range of ±3%. The reliability and durability of the rechargeable batteries are proven can support the system for 16 hours without sunlight present. The package loss has increased when the distance becomes longer.
