5V input, Analog or Digital output Easy interfacing, durable, enclosed by lens, easily replicable 10 meter PIR: 116° of viewing up to 10meters Slight Motion PIR: 102° of view up to 2meters

 To design a system that uses a Passive Infrared Sensors to detect a real threat to the vehicle. An array of PIRs shall be mounted in the under carriage pointed in a direction that allows for complete coverage under the vehicle. The sensors will only be deployed when the alarm is activated.

 6061 machined Aluminum housing  Rubber O-ring seals for cover and side door  5V mini linear actuator 30mm stroke  PCB boards mounted on either side of actuator  Actuator extends PIR into open view when vehicle is shut off and armed with NAVATA system
