In this research we are doing a water quality measurement for monitoring the water in different area by using various sensors like temperature, turbidity, pH sensor which will help us to collect the parameters of the water. A rduino (nano) gather that parameters and send it to the raspberry pi3 through Wi-Fi module and then raspberry pi will process the data and compare that data with the threshold value of the sensors. For these transfers of information through raspberry pi and user is takes place using MQTT protocol, MQTT stands for Message Queuing Telemetry Transport.

Keywords : Internet of Things (IoT), Arduino, Raspberry Pi, Naive Baye’s, MQTT protocol etc.
