NEW! The BLUEPYRO-M3225 is an ultra low-power, miniature (22 x 15mm), low profile motion/proximity detection System on Module.

  • It is an integration of an I-SYST BLYST Nano Bluetooth(R) 5 module with an Excelitas PYD2592, a dual element PIR sensor with digital output and wake-up/sleep mode functionality.
  • With a 64MHz Nordic nRF52832 ARM(R) M4F at its core and 27 programmable GPIO, it is the perfect solution for fast times to market, while addressing the growing global demands for additional sensor functionality and connectivity, particularly in support of low-power, low-cost, industrial design, IoT application requirements.
  • A fully open-source SDK is available for writing user application firmware directly on the module. Hence eliminating the requirement of an external MCU, reducing costs and time to market.






The PYD 2592 is a parallel opposed format, two elements detector based on fully RohS compliant pyroelectric material. The signal is converted to a digital value using Sigma-Delta and DSP techniques. A configurable motion detection unit is implemented. Once motion was detected, an interrupt will be sent to the host system. Putting the host system to sleep an overall ultra low power consumption will be achieved. All data is accessible by the host system to enable advanced signal analysis with your own detection criteria.

  • Integrated digitization
  • Motion detection unit with Interrupt function
