AIM OF PROJECT

TO DEVELOP WIRELESS INDUSTRIAL MONITORING SYSTEM USING SENSOR

INTRODUCTION

•A transformative advancement in the field of sensor technology has been the development of sensor systems.

• The term Smart Sensor was actually invented in the mid-1980.

• SENSOR is a device that detects and responds to some type of input from the physical environment such as light, heat etc… or any one of a great number of other environmental phenomena”

• Sensor devices that are “small in size and able to sense, process data, and communicate with each other, typically over an RF channel.

• LPC2129 MICROCONTROLER

• TEMPERATURE SENSOR(LM35)

• CO2 SENSOR(MQ-7)

• LDR SENSOR

• COLOUR SENSOR(TCS3200)

• ZIGBEE

• 2X16 LCD

• BUZZER

LPC-2129

32-bit ARM7TDMI-S microcontroller.

16 kB on-chip Static RAM

256 kB on-chip Flash Program Memory.

128-bit wide Interface/accelerator enables high speed 60 MHz operation.

32-bit 2-timers, 4-channel 10-bit ADC, 2 advanced CAN channels, PWM channels.

SENSORSLIGHT DEPENDENT RESISTOR: Light-controlled variable resistor, The

resistance of a photo-resistor decreases with increasing incident light intensity

TEMPERATURE SENSOR(LM35):Precision integrated-circuit temperature sensors, with an output voltage linearly proportional to the Centigrade temperature. Linear + 10 mV/°C Scale Factor.

CARBON DIOXIDE SENSOR(MQ-7):A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. Sensitive components consist of 2 parts: 1}Heating circuit having time control function.2}The signal output circuit; it can accurately respond changes of surface resistance of the sensor.

COLOR SENSOR(TCS3200):The TCS3200 programmable colour light-to-frequency converters that combine configurable silicon photodiodes and a current-to-frequency converter. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity

ZIGBEEModel is designed with low to medium transmit power and for high reliability wireless network.

Range: up to 30m with directional antenna.

RF DATA RATE:250Kbps.

FREQUENCY BAND:2.4000 – 2.4835 GHz

POWER SUPPLY

*7805 is a 5V fixed three terminal positive voltage regulator IC.

*The IC has features such as safe operating area protection, thermal shut down, internal current limiting which makes the IC very rugged

DATA ACQUISTIONS RECEIVED BY SENSORS IN REAL TIME

THE INTERFACE EXTRACTS DATA FROM THE SENSORS, COMMANDS THE ACTUATOR, AND PROVIDES A DATA COMMUNICATION INTERFACE TO THE CENTRAL CONTROL UNIT.

THE GATEWAY WILL COLLECT RESULTS FROM THE SENSORS AND RELAY THEM TO THE DATABASE.

SMART SENSORS IMPLEMENTATION TO LPC-2129 NOT ONLY ACQUIRES DATA BUT ALERTS THE CONTROL UNIT TO TAKE NECESSARY ACTIONS TO PERFORM

WORKING PRINCIPLE

ADVANTAGE Reduces the need of Caretakers. No wired connection is required. Time Savings, Continuous & efficient

monitoring. Low Power Consumption Portable and can be changed as per our

requirement unlike the Wired ones.

Monitoring Range is less. Battery consumption is more due to

simultaneous data transfer.

DISADVANTAGE

Application Remote monitoring and alerting.

Store and forward applications like TEMPERATURE,CO2 monitoring

require a long distance wireless link with network coverage over its

entire operation area.

Environment monitoring in closed loop area like boilers .

Chemical and Pharmacy companies use color sensor to detect color

using manufacture of drugs.

CONCLUSION

• The main intend of interfacing diverse primary sensors with the smart sensor interface unit using Serial peripheral interface and wireless communication has been achieved successfully.

• The Colour, Temperature, CO2 and LDR sensor are used provides linear results experimentally.

• The RF module provides the maximum line of sight 30 meters range for wireless communication.

• The central monitoring system which is consisting of Master & slave in the smart sensor platform reduces the human efforts and cost to a large extent.

• These dynamic features of smart sensors can provide the critical data to the end user in a more rapid, reliable, robust, economical and efficient way

FUTURE SCOPE

INTELLIGENT SENSORS CAN BE MONITORED AND CONTOLLED IN IOT ENVIRONMENT

CAN CREATE SENSOR NETWORKS BY DEPLOYING IN INDUSTRY,AGRICULTURE AND ENVIROMENT TO ACUIRE DATA & STORE FOR FUTURE REFERNCE
