- Use BISS0001 signal processing IC, sanyo genius regulator
Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc.
- Automatic detecting: the output will be high when objects enter the sensing range, and automatically turn to low when object leave
- Photosensitive control (optional, not factory-set yet) can be set.
- Temperature compensation (optional, factory reset): In the summer when the ambient temperature rises to 30 ° C to 32 ° C, the detection distance is slightly shorter, temperature compensation can be used for performance compensation.
- Working mode (set by jumper)
- Non-repeatable trigger/ delay mode (set to LOW): the sensor will turn to low TTL after the delay, even the sensing object is still in range.
- Repeatable trigger (set to HIGH): the sensor will not turn to low if the object still staty in the sensing range in the delay time.
- Wide operating voltage range: default voltage DC4.5V-20V.
- Micro-amp power level consumption: static current <50 microamps, particularly suitable for battery-powered automatic control products.
- Output high signal: easy to achieve docking with the various types of circuit.
