ZMOTION MCU’s & S/W
ZMOTION microcontrollers are optimized for PIR sensor applications. Integrated Op Amps, comparators, internal voltage reference systems and sigma/delta or high-resolution SAR ADC convertors make them ideal for many motion detection applications.

In addition to motion detection, the ZMOTION microcontroller can be used to perform additional tasks as required by the application.

  • Switch or potentiometer input monitoring
  • TRIAC/MOSFET/Relay control and zero-cross detection
  • Multi-color LED control via PWM
  • Real time control of motion sensitivity and Engine operation
  • RF communication protocols
  • Ambient light, temperature, humidity sensing
  • Real time control of motion sensitivity and Engine
  • DALI/DMX/1-10V/PWM intelligent lighting protocols
