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.
- Based on passive infrared (PIR) sensor
- Triggers a LED when motion is detected
- Firmware for the NUCLEO-L053R8 development board using the IAR development environment
- Free, user-friendly license terms
