Murata Develops World's Smallest Pyroelectric Infrared Sensor - Feature Rich Device Ideal for Smart Energy Applications
Smyrna, GA, February 23, 2010 - Murata Electronics North America, a world-leading innovator in electronics and the largest global supplier of ceramic passive components, today introduced the world’s smallest pyroelectric infrared (PIR) sensor. The new sensor (global part number IRS-B210ST01-R1) measures 5.0mm x 4.7mm x 2.4mm, making it ideal for use in compact, low profile electronic equipment and, in particular, energy saving devices. As the only surface mount PIR sensor available on the market today, it provides numerous features including high sensitivity and signal to noise ratio, excellent stability against temperature changes and white light and enhanced radio frequency interference (RFI) immunity.
The many design benefits of the compact component make it well suited for a variety of security and lighting applications to further help homeowners and businesses decrease energy consumption. For example, Murata’s sensors have the ability to detect infrared emitted by the human body for security sensing applications. Also, the component can be utilized in household appliances, such as lighting, which switch off automatically when no one is in proximity to further save energy.
“Murata’s PIR sensor is on the cutting edge of energy saving technologies,” stated Peter Tiller, senior group product manager for Murata Electronics North America. “With green applications being an important part of America’s economic recovery, Murata is pleased to offer the advanced sensor to our customers.”
The PIR sensor includes dual 0.85mm x 1.2mm electrodes with a field of vision of ±70º (horizontal) and ±50º (vertical). Its operating temperature range is -40 to +70ºC and the device is driven by supply voltage in the range of 2V to 15V.
Murata’s IRS-B210ST01-RI sample price is $1.88 and the lead-time is approximately 12 weeks. Additional purchasing info can be found online at www.murata-northamerica.com.
In addition to the new PIR sensor, Murata has developed a large range of sensing technologies. Using piezoelectric ceramics and magnetic resistive elements, Murata’s sensors can detect heat, infrared, ultrasonic waves, vibration, acceleration, angular velocity, angular rotation, rotation, magnetism and electrical fields. These products are used in a variety of applications such as white goods, audio/visual electronics and automotive. All are designed to improve the users experience and ease of use.
