Nippon Ceramic Co., Ltd.

Nippon Ceramic Co., Ltd. will start offering the samples of its
brand-new digital communication PIR sensor, the D-Pyro™.
Nippon Ceramic CO., Ltd., Tottori, Japan, is delighted to announce that it will start offering the samples ofD-Pyro™ which is a digital communication passive infrared sensor (PIR sensor) required no analog circuits.
The D-Pyro™ is the perfect solution to be mounted on human motion detector for security, energy
management, or surveillance camera system.

PIR sensor is essential for human motion detector for security and automatic
lighting control, security camera wake-up, or energy-saving HVAC system. It
converts weak infrared rays emitted from the human body into electric signals
and requires large amplification and circuit design in each application to process
the outputted electric signals. D-Pyro™ achieves to incorporate all the processing
circuit into TO-5 package, and enables various settings by software through thedirect communications between the customer’s host MCU and the sensor.
[Product Features]
1) Highly Versatile Digital Communication Method
UART or I2C communication are available and both has the function of a serial communication with the hostMCU. UART type can also be used as on/off output type.
2) Low-power Consumption for the Buttery-powered System
Perfect for the application of the buttery-powered wireless system as the current consumption in a steadystate is only 2.5μA. The range of the power supply voltage is also wide, from 1.8V to 5.5V.
3) Wake-up Trigger Function
The wake-up trigger function allows the host MCU to minimize its power consumption for the energy savingof the whole system.
4) Peak Hold Function
I2C type holds a ±11bit peak value between the previous and the current data reading. The host MCU will
never miss the peak value both in the sleep-mode and in the normal operation. It also enables to lighten
the processing load of the MCU by taking longer intervals of data read request.
5) Set the Amplification Characteristics by Software
The amplification characteristics can be selected from 12 choices by setting the digital band-pass filter ofthe sensor by the host MCU.

6) Excellent EMC Performance
D-Pyro™ has an excellent performance against the electromagnetic noises from the outside as all theprocessing circuit is incorporated into TO-5 package.
7) Set Several Sensors on the Same Bus Line
When the several motion sensors are required to be used in one system, especially for the application ofwide-area surveillance or highly reliable security equipment, multiple D-Pyro™ (I2C type) are able to beconnected to the same bus line. It enables to eliminate several components and only one bus line is requiredas the interface of the MCU.

8) SMD is Available
Surface mount type is available in addition to TO-5 package type.
