Door Opening / Closing Detection
USE CASES
Tri-axis magnetic sensor, AK0997x is the most suitable sensor for measuring strong magnetic fields in magnets.
It achieves very low current consumption, so the AK0997x is ideal for battery-operated products that require long-term continuous operation. It also integrates a flexible switch function, which can contribute to downsizing and long life of IoT products such as window or door opening/closing detection.
Demo videos show opening/closing detection, detection mechanism, application, and demo kit.
#01
What is this Demo?
- Did you lock up?
- Monitor shows "Close"
- When door opening by someone,
- Monitor turns to "Open"
- Try to tamper by external magnet,
- Monitor shows "Alart"
#02
How to detect?
- Mount the magnet on the door, and the sensor on the frame
- Sensor detects magnetic field
- By Opening the door, it decreases magnetic field applied to sensor
- Detect door state by this change
- Bring the external magnet closer, magnetic field was applied over the threshold
- Detect magnetic tamper
- Detect mT order 3D magnetic field
- Variable thresholds can be set for switch
#03
What application for?
- Security sensor for door/window
- Detect an intruder
- IoT Toilet
- Detect the restroom stall vacant or not
- Wake up trigger for mobile goods
- Detect laptop Opening/Closing
#04
Detail of Demo kit
- Using Magnet and Demo kit
- Start and set up Smartphone Apps
- Place Magnet and Demo kit to the door
- From Closing to Opening
- "Close" state turns to "Open" state
- In case of external magnet approached, turns to "Alert" by exceeding magnetic threshold
