CONTENTSINTRODUCTIONBLOCK DIAGRAMFLOW CHARTCIRCUIT DESCRIPTION

INTRODUCTIONDeveloping a device capable of sensing motion of a

paralyzed person under observation.Use GSM technology with PIR sensor to alert doctor

with motion of a patient.Motion sensing is using PIR sensor(passive infra red

sensor)Used components are PIRsensor, PIC

microcontroller(PIC16F877A),GSM modem,LCD.Blood pressure is measured using blood pressure

sensing unit.

CIRCUIT DESCRIPTIONPIR sensor-(passive infra red sensor)measures

infrared light radiating from objects.Use in the construction of PIR based motion

detectors.Apparent motion is detected when a infrared source

with one temperature such as human passes in front of an infrared source with another temperature such as a wall.

Sensor detects the heat from the object passing infront of it.

The object breaks the field with the sensor determined by normal state.

Microcontroller used is PIC16F877ACMOS FLASH –based 8-bit microcontroller.200ns instruction execution,256 bytes

EEPROM data memory.2 comparators,8-channel of 10 bit ADC,2

capture /compare/pwm function, Serial port is either 3 wire spi/2 wire i2cbus,a

USART, and parallel slave port.

GSM modem is used for calling doctor.Using DTMF technology.Designed for control signals only.DTMF tone controlled by AT command

RESULT RECENT DEVELOPMENTFabricated 50% of the pcb lay out using orcad software.Studied half of the programme. FUTURE DEVELOPMENT• Wiring of circuit and checking the output.• Assembling of circuit.• Program development.• Final Product development
