Parameter debugging method
* VO: Detection level output. When a person or an object is detected to move, it outputs a high level for about 1 second. Low level when there is no object moving.
* GND: Ground.
* VCC: Power supply. The version with LDO is powered by a 5V power supply.The FOV of the test person's movement about 1 meter above the ground in different configurations is as follows:
1. Sensitivity debugging method A
Sensitivity adjustment can be achieved by changing the magnification of the comparator. The calculation formula is (R12/R11)*(R13/R6). The test sensitivity can be adjusted by changing the resistance of R6 or R11. The larger the multiple, the more sensitive and the longer the test distance.
2. Block time debugging method
A1. Output delay time Tx: 49152*R14*C7, which means the high level duration when the moving target is detected.
; A2. Trigger lockout time Ti: 24*R8*C9, meaning that after the detection is completed, it needs to pass the trigger lockout time and then perform the next test. The user can follow DSP and scene need to debug output delay time and trigger block time.
The delay time and blocking time are shown in the figure below, VS is the moving target in the detection area, high level means movement, and low level means static. VO is the sensor output alarm signal.
