Door Sensor Is someone at my door? My child is home alone, but I’d like to know if he is safe. I ordered a pizza, but I don’t have a doorbell and can’t hear a knock. Proximity sensor Was someone in my workstation? How long were they at my computer? Is someone too close to something they shouldn’t be? (a piece of art in a museum possibly)

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, , or instant message.

Detects an object Records distance via an Infrared Sensor Continuously transmits the distance of an object to the 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
