How We Answered These Questions

Wireless Proximity Alert System• Detects an object within 80 cm of sensor• Can be programmed to record for a certain

amount of time before generating an alert• Records and transmits the distance of the object

and the time the object remained in front of the sensor.

• Programmable alert system allows alerts to be sent via text message, email, or instant message.

Transmitter

• Detects an object• Records distance

via an Infrared Sensor

• Continuously transmits the distance of an object to the receiver

Receiver• Receives distance data

from the transmitter• Waits until a pre-

programmed ‘threshold’ amount of time an object was near the sensor

• Generates an alert to be sent through desired alert channels complete with time the object was near the sensor and distance the object was from the sensor
