This firmware takes the signal generated by a passive infrared (PIR) sensor on the STEVAL-IDI009V1 evaluation board to trigger the user LED on the NUCLEO-L053R8 development board.
Common applications include home automation systems, where human detection by the sensor triggers alarms and room lighting.
The board embeds a TSU102 operational amplifier, which consumes only 1 µA, rendering it highly suitable for battery powered applications like LED lighting with embedded motion detection.
The entire application consumes only 24 µA when there is no detection.
All features
Based on passive infrared (PIR) sensor
Triggers a LED when motion is detected
