Mini Motion/Daylight Ceiling Sensor-DIM Kit

  • Combines passive infrared and ultrasonic technology providing the most accurate motion ceiling sensor possible. The ultrasonic sensor can defect fine movements such as typing, and flipping book pages.
  • The ceiling sensor is designed to be mounted about 8-10 feet off the ground. The implementation of two sensing technologies in each unit helps to avoid false triggering while still accurately sensing motion.
  • 6 different trigger modes that use a combination of both PIR and ultrasonic sensor. Has adjustable time delays via dip switch (5 sec - 30 min).
  • Multi-level Coverage, up to 1, 600 ft² PIR coverage and up to 1000 ft² ultrasonic coverage.
  • UL/ CUL Listed. Operating temperature (32 – 131°F).
  • California Title 20 and 24 compliant. 120/277 VAC, 1/4HP-120VAC.

PING Ultrasonic Distance Sensor

  • Our PING))) ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. A single I/O pin is used to trigger an ultrasonic burst (well above human hearing) and then "listen" for the echo return pulse. The sensor measures the time required for the echo return, and returns this value to the microcontroller as a variable-width pulse via the same I/O pin.
