Motion Detector Test Results Purpose: This document contains the test results for Phase 2 detector. Summary: The motion sensor works well and meets standby current spec <42.3uA average. It also works well over target voltage range of VDD = 2.7V to 3.5V using an E1 emulator, CR123 battery or external power supply. Some initial setup of 3 pot settings is required. Test Results as per Test Spec: TEST 1. Motion detector will be placed near the edge of a countertop or table top at 24”-36” above the floor. Motion detector PIR sensors will pointed out in a horizontal direction and should not be obstructed by the table edge or countertop edge. The tests will be performed in an area where there is no direct sunlight and no heat/IR lamps present. RESULTS OK. EXPLANTION MikeC. (12Mar2014) For initial calibration, download SW with E1 emulator set for 3V power. (typically VDD = 3.3V-3.5V). Then set JP11 pot for IVREF0 (DNI_J2, Pin 12) = 0.86Volt and set JP10 pot for IVREF1 (DNI_J3, pin 1) = 2.3Volt. Set JP9 pot for about 50% 2. A human with mass of 50kg or greater can be the test subject and can be used to roughly calibrate the Motion sensor. First the potentiometer gain should be set to minimum setting and with the test subject standing 4 meters (~13 ft), the PIR 2nd stage pot gain should be increased to where the motion alarm starts to sound. 3. After calibration a human subject should approach the PIR sensor from a distance greater than 6 meters from 5 different angles described on the surface of a 90 degree circular cone with the apex point of the cone intersecting the surface of the PIR sensor: a. Straight on axis to the PIR sensor. b. From >70 degrees off-axis to the right (“3 o’clock“ position) to the 45 c. From >70 degrees off-axis to the left (“9 o’clock“ position) d. From >45 degrees off-axis down toward the floor (“6 o’clock“ position) e. From >45 degrees off-axis above the Motion sensor (“12 o’clock“ position) If I set the AMP0O gain for max value, I can get motion detection at about 4.5-5Meter for on axis placement and about 3Meter distance at 70 degrees off axis. If I set the AMP0O gain for max value, I can get motion detection at about 4.5-5Meter for on axis placement and about 3Meter distance at 70 degrees off axis and greater distance (4Meter?) for +/-45 degrees. (mid-point) of rotation. CW rotation of JP9 increases motion sensitivity. With 3V power supply (battery or external power), the Comparator reference voltages (IVREF0 and IVREF1) will drop by about 10-15% relative to E1 power supply (VDD = 3.4V-3.5V) MikeC. (12Mar2014) AMP0O set at max gain (JP9 at full CW position) is probably too sensitive and may result in false Motion sensing. 4. At the angle and distance the alarm sounds, the approximate distance should be measured, and should at least (and is allowed to be greater than) 3 meters distance minimum and at an angle =/> 45 degrees from the on-axis line 5. When the detector senses motion, it should alarm for a minimum of 1 sec and keep the alarm on for a minimum of 1 sec after motion ceases to be detected and continuously when motion is detected otherwise. 6. Then to test the motion velocity sensitivity, the motion detector is allowed to alarm from any movement of the Human subject, but is not required to do so for motion velocities < 0.05 m/sec or >5m/sec. 7. Also for the PIR sensitivity test, a human subject inside the maximum detection range of the motion detector should not trigger the alarm if the subject is completely motionless. 8. Fluorescent or CF lighting outside the 3 meter radius of the sensor should not trigger the PIR sensors 9. Confirm that pushing the SW1 button (added on the Phase 2 Motion sensor board) will sound the alarm as long as the button is pressed and turn off when SW1 button is released (assuming no motion in front of sensor). 10. Current drain measurements and associated duty cycles for each type MCU operation will be measured for the Motion sensor operation in: a. Standby mode with no motion in the field of If I set the AMP0O gain for max value, I can get motion detection at about 4.5-5Meter for on axis placement and about 3Meter distance at 70 degrees off axis. When motion is sensed, the alarm stays on for a minimum of 2 seconds With the human subject motionless, the Motion sensor does not alarm Fluorescent lightning does not cause motion alarm MikeC. (12Mar2014) Works MikeC. (12Mar2014) a. Standby current is about 3034uA. Out of this, about 19- Motion sensor runs with an E1 OCD emulator, or with the CR123 battery inserted into the battery holder or with sensor detection. Target is to achieve < 42.8uA average current drain b. With motion in the field of sensor detection. 20uA is current drain into the PIR sensor itself thru R87, 47K resistor. b. Alarm mode current ~66mA at VDD = 2.9V3.0V with external power supply external power supply jumpered to battery holder. When measuring current drain with external power supply, make sure keep milliameter on high milliamp scale to allow 5070mA (alarm current). Many milliameters will starve the current drain when on 200uA max or 2mA full scale ranges. When starving the current, VDD voltage drops too low and causes RL78 LVD reset @~2.5Volt (set by FW).
