Specification Brand : CTWHA BulletPoint1 : Fully automatic sensing: Input high level when someone enters its sensing range, and turn off the high level automatically with a delay when the person leaves the sensing range. Output low level. BulletPoint2 : Photosensitive control (optional): The module has a reserved position to set the photosensitive control, not sensing during the day or when the light is strong. The photosensitive control is optional, and the photoresistor is not installed at the factory. If you need, please buy photoresistor separately and install it by yourself. BulletPoint3 : Wide operating voltage range: default operating voltage DC5V to 20V Micro power consumption: quiescent current of 60 microamps, especially suitable for dry battery powered electrical products. Output high level signal: can be easily realized with all kinds of circuits. BulletPoint4 : Self‑developed anti‑jamming chip, anti‑jamming performance is significantly improved. BulletPoint5 : High‑quality compatibility, widely used for measuring hydraulic, oil pressure, air pressure, water pressure and other media.
