Santhosh Varma 1 Kavi Priya 1 ECE/Sathyabama university Chennai, INDIA This project deals with categorising the quality and estimating the quantity of the milk using Ph sensor and Level sensor and to transfer the entire data to the dairy farm PC using Zigbee communication. Milk is very important due to its special nutritive value and important role for human and animal health. The paper aimed to present some aspects regarding milk quality and quantity estimation The existing milk analysers categorises the milk based on the quantity level only .So High quality milk does not contain its value, because treated as quantity based. So in this proposed system each customer should have their own card for accessing the milk diaries. High quality milk should have good density, so density of the milk is measured by using an intensity sensor and also level of the milk will be measured by using a level sensor. The amount is credited based upon the quantity (level) and quality (intensity) of the milk, which is sent through the Zigbee. High quality milk will be stored in one tin can and others will be stored in another tin can. Cost can also be estimated easily by this technology. https://www.biotech-asia.org/vol12no2/categorising-the-quality-and-estimating-the-quantity-of-the-milk-by-embedded-system-using-zigbee/ Dairy panel;Sensors;Corrected lactometer reading;Electronic milko testers;Radiofrequency identification
