SunFounder Thales Kit for Raspberry Pi Pico, Release 1.0
Distance Adjustment
Turning the knob of the distance adjustment potentiometer clockwise, the range of sensing distance increases, and the
maximum sensing distance range is about 0-7 meters. If turn it anticlockwise, the range of sensing distance is reduced,
and the minimum sensing distance range is about 0-3 meters.
Delay adjustment
Rotate the knob of the delay adjustment potentiometer clockwise, you can also see the sensing delay increasing. The
maximum of the sensing delay can reach up to 300s. On the contrary, if rotate it anticlockwise, you can shorten the
delay with a minimum of 5s.
Two Trigger Modes
Choosing different modes by using the jumper cap.
• H : Repeatable trigger mode, after sensing the human body, the module outputs high level. During the subsequent
delay period, if somebody enters the sensing range,the output will keep being the high level.
• L Non-repeatable trigger mode, outputs high level when it senses the human body. After the delay, the output
will change from high level into low level automatically.
