The STEVAL-IDI009V1 evaluation board conditions the signal generated by a passive infrared (PIR) sensor, for common applications like human detection. A person in range of the sensor triggers a detection event, which can in turn be used to trip an alarm or command room lighting to be turned on, for example.
The board embeds the TSU102 operational amplifier which consumes only 1 µA. It is highly suitable for battery powered applications such as LED lighting with embedded motion detection to enhance daily comfort.
The global application consumes only 24 µA when there is no detection.
