Door Opening / Closing Detection

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.

Tri-axis Magnetic Sensors

#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

[Note] AK09973 is recommended instead of AK09970.
