Real-Time Milk Condition Surveillance System

Milk adulteration has become a major health-related issue. This issue can be resolved using the internet of things which is a broad topic that started to cover almost a breadth of every technological advancement in recent years. At this point, it is essential to introduce the benefits and functionalities of using Internet of Things (IoT) devices to serve nutritional purposes. Our aim in this paper is to construct a quality monitoring system based on IoT which will ensure the quality of milk which is a common dairy product. Our focus is to monitor the quality of milk-based on pH value, moisture, alcohol presence, checking light intensity, temperature, and humidity test. Blynk app is used as the IoT platform whether the user is able to see the real-time values of all the parameters including the values fetched from MQ3, pH, LDR and DHT11 sensors. Serial communication is also being established between Arduino mega and nodemcu for dynamic sensor data transmission. Milk quality monitoring is a relevant field nowadays due to the large numbers of adulterated foods being detected in Bangladesh.
