- Operating voltage: DC 4.5V to 20V
- Quiescent Current <50uA
- Level output: high 3.3V/ low 0V
- Delay Time: adjustable (5 seconds to 200 seconds)
- Trigger: L can not be repeated, H can be repeated, the default value is H
- Sensing range: <120 degrees angle, 7 meters
- Operating temperature: -15 ~ +70 degrees
- PCB Dimensions: 32mm * 24mm, the screw hole distance 28mm, screw diameter 2mm, sensor lens size: (diameter): 23mm
- Automatic induction: When some people enter into its high sensing range, sensing range of people leaving the automatic delay off high. Output low.
- Photosensitive control (not installed) can be set during the day or light intensity without induction. Module is reserved for position sensitive resistor is not installed. If required, Install at your own photoresistor.- Contact us,We can help provide resistance
- Two trigger modes: L can not be repeated, H can be repeated. Can be jumper selected, the default is H.
A. trigger can not be repeated: the sensor output high, the delay time is over, the output will automatically from high to low.
B. repeatable trigger: the sensor output high after the delay period, if human activities in its sensing range, the output will remain high until after the delay to leave the high Level goes low (sensor module detects the human body every activity will be automatically extended after a delay time and the time of the last event the starting point for the delay time).
- With induction blocking time (the default setting: 0.2 sec): induction module, after each sensor output (high to low), can be followed by a block of time set in this period of time not to receive sensor Any sensor signal. This feature can be achieved (the output time and the blockade of induction time), the interval between the work can be applied to interval detection products; the same time this feature can inhibit the process of load switching for a variety of interference.
- Output level signal: easy docking with the various types of circuits
