WIRELESS MONITORING SYSTEM FOR COLD STORAGE

ABSTRACT:

As RF is t technology in wireless field, we had tried to demonstrate its way of functionality and various aspects like kinds, advantages and disadvantages using a small application of controlling the any kind of electronic devices and machines. The RF technology is broadly adopted for bulk and fast data transmission over a dedicated channel.

DESCRIPTION:

In this project we are demonstrating the working principle of RF module are controlling the devices connected by continuously monitoring them. Here we are continuously monitoring the temperature of a room. In this project one RF module is connected to the PC through which we can transmit the data. The other RF module is interfaced to the microcontroller. LM 35 is used for temperature sensing, ADC 0804 is used for converting the analog temperature to digital. The micro-controller reads the temperature through the ADC and transmits to the host.
