Skycraft Surplus Show all Sensitivity Adjustment (Sx): Turning clockwise increases the detection range (up to 7 meters). Time-Delay Adjustment (Tx): Controls how long the output remains HIGH after detection. Turning clockwise increases the delay. Trigger Mode Jumper: L (Single Trigger): The output goes low immediately after the delay time ends, even if motion continues. H (Repeat Trigger): The output remains HIGH as long as motion is detected within the sensing range. Key Features for Advanced Users Day/Night Sensing: The board often includes an unpopulated port for a
