Features: Automatic induction: When someone enters the induction range, he enters a high level, and when he leaves the induction range, he automatically delays closing the high level. Photosensitive control (optional): Module reserved position, can be set up photosensitive control, day or light intensity is not sensitive. Two trigger modes: L is not repeatable and H can be repeated. Jumper selection, defaults to H Inductive blocking time (default setting: 3-4 seconds). Wide operating voltage range: default operating voltage DC5V to 20V Micro power consumption: quiescent current 65 microamps, especially suitable for dry battery powered electrical products. Output high level signal: it can be easily connected with all kinds of circuits.
