Monitoring System for Frozen Food and Pharmaceutical Products during Transit using 1-wire Protocol: Design and Implementation

Purpose of monitoring parameters like temperature and humidity can be done with help of techniques like RFID based or Wi-sensors based systems. Such systems are not suitable in environment that is dusty, dirty and polluted. Due to above lacunas the proposed system is introduced. Propagation abilities are affected due to antenna parameter interference. Propagation abilities affected due to presence of large quantity of water is surely eliminated. The temperature of shipment is recorded by thermochron DS1921G and humidity sensor DHT11 that implements 1-wire protocol authentication purposes are served by thermochron so as to provide security as well as multitasking temperature monitoring. This proposed system exhibits the use of 1-wire protocol for the monitoring of pharmaceutical products and frozen food during transit. Micro- controller of ARM7 family LPC 2148FBD64 will be used at the heart of the system. Tracing of shipment will be done using GPS technology and notifying user by GSM technologies. To design and implement a system for monitoring temperature and humidity and recording the latitude and longitude (location) at particular time during transit is the main purpose of this paper. The monitoring system will be stored inside the cool box.
