Evaluation board for passive infrared sensor signal conditioning
based on TSU102
Features
Allows motion detection with PIR sensor
Suitable for home automation applications
Based on TSU102 operational amplifier
Band pass filter bandwidth from 0.7 Hz to 5
Hz
Only 24 µA current consumption
With Fresnel lens to widen detection area
Compatible with NUCLEO boards
Compatible with Arduino UNO R3
RoHS compliant
Description
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.
