MOTION SENSOR

Passive infrared motion sensors can be very useful alarm sensors.  But, in a boat careful placement of the sensor is critical to prevent false alarms. If possible, mount the sensor overhead so it’s looking down. An alternative is to mount it low in the boat so it can not see outside the boat.  The field of view for this sensor is a flat curtain that is about 6 feet wide at a distance of 12 ft. The motion sensor detects well beyond 12 feet. Keep heat sources out of the sensors field of view. Technical advances for this PIR have all but virtually eliminated false alarms from environmental disturbances.
