Smart and cost-effective solutions for water quality monitoring are gaining attention with the recent advancement in information and communication system technology.  This paper aims at the design and development of the internet of things (IoT) based low-cost and portable water quality and quantity monitoring (WQQM) system. The proposed system not only monitors the water quality but also monitors the amount of water being utilized by the consumer. The main objective of designing WQQM is to ensure both purity and conservation of water. The water quality meter measures six qualitative parameters of water viz. potential hydrogen (pH), water temperature, atmospheric temperature, turbidity, and total dissolved solids (TDS). Whereas, the water quantity meter measures the water level and water flow to calculate the amount of water being used.  A custom printed circuit board (PCB) is designed to integrate all the sensors for quality and quantity measurement. The results generated by the WQQM system are wirelessly transferred, using Wi-Fi, to the online monitoring system.
