  1. A CHILD-LEFT-BEHIND WARNING SYSTEM BASED ON CAPACITIVE SENSING PRINCIPLE

  2. AIM: “A CHILD LEFT BEHIND WARNING SYSTEM BASED ON CAPATIVESENSING PRINCIPLE”.

  3. COMPONENTS: • LPC 2148(ARM7) • Sensors • GSM • LCD • Ignition switch.

  4. EXISTING METHOD: • Once a car is turned-off and parked, keeping its window • glass closed, the temperature inside the car increases • rapidly even on a day with atmospheric temperature of • about 21degree centigrade. • As the thermoregulatory system of the child’s not well • developed, this condition may lead to heatstroke • which can be fatal. • As we know, the child entire depends on elders but, • unknowingly, in a busy schedule, the driver or passengers • may forget to take the child in the front seat, usually • kept in a back seat of the car.

  5. PR0POSED METHOD: • Here we proposed a simple and compact capacitive sensor that can be placed in front seat to detect presence of a child. • The proposed system also has a vehicle ignition monitor to confirm presence of driver inside a car. • It also has a temperature inside the car. A GSM modem is used to alert driver/parents/guardians as soon as a child left in the car in front seat is detected and the car is found to be turned-off. • Principle of operation of the capacitive sensor, measurement scheme employed details of the prototype sensor and warning system (through SMS or Voice announcement) developed and tested.

  7. SOFTWARE : Embedded ‘C’ TOOLS :Keil IDE, Flash magic TARGET DEVICE : LPC2148 (ARM7) APPLICATIONS : Industrial areas, Coal mine environments, Leakage environments.

  8. ADVANTAGES: low cost, • long distance networks • REFERENCE: • User manual of ARM7 TDMI-S. • Data sheets of GPS, GPRS.
