Abstract

Environment Monitoring System project is developed for the users to control a Robot with Humidity sensor, Fire sensor and metal detector. The user can control the movements of the robot like hand up, hand down, Left and right.

When the user presses a specific button of the computer, a signal corresponding to the operation is sent through serial port. The microcontroller receives the signal through serial port and controls the multi channel RF transmitter.

The RF transmitter connected with the ROBOT receives the signal and sends to the microcontroller. The microcontroller analyses the signal and accordingly it operates the relays in the external electronic circuit through driver section. The relay is used as a switch to operate the particular motor in the Robot. By this way the user can control any of the operations of the Robot.

The sensors connected in the Robot senses the humidity, fire and metals. If it senses any thing, it sends signal through RF transmitter. The RF receiver connected with the PC receives the data and displays about the critical situation. It stores the data in the PC.

The design and port programs are written in Visual Basic. The microcontroller program is done in assembly language. The microcontroller used is PIC 16F73
