Abstract:
An embedded system is a special-purpose computer system designed to perform a dedicated function. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded system comprises of both hardware and software. Embedded system is fast growing technology in various fields like industrial automation, home appliances, automobiles, aeronautics etc. Embedded technology uses PC or a controller to do the specified task and the programming is done using assembly language programming or embedded.
Many devices are used for monitoring the humidity conditions. In early days, all the systems are analog devices and the measured value can be displayed by using recorders, and CROs.
This project is used to eliminate the drawbacks in the existing system. Here the humidity is monitored by sensor that can be converted in to corressponding signal to the microcontroller.
The main feature of this project is that, according to the humidity levels, the controller activates the relay driver unit and pumps the motor by using relay switches. The controller also generates signal corresponding to the humidity level, and then the signal can be transmitted through the gsm modem to mobile. when the pump is ON the corresponding message will be forwarded to our mobile number which was already programmed in controller unit.
