Pyroelectric Infrared Sensor measures 5.0 x 4.7 x 2.4 mm.
January 13, 2010 -
Surface-mount IRS-B210ST01-R1 sensor detects infrared at wavelength emitted by human body, enabling person detection for security and proximity sensing applications. It features dual 0.85 x 1.2 mm electrodes with ±70° horizontal and ±50° vertical field of vision. Driven by 2-15 V supply voltage, device operates in -40 to +70°C range and features enhanced RFI immunity. It can be used in household appliances, such as lighting, to switch them off automatically when there is no one in proximity.

Murata Announces World's Smallest Pyroelectric Infrared Sensor
Hoofddorp, Netherlands: The latest version of Murata's pyroelectric infrared (PIR) sensor is the world's smallest at just 5.0 x 4.7 x 2.4 mm, enabling the sensor to be used in compact, low profile electronic devices and equipment. The IRS-B210ST01-R1 is also the only surface-mount PIR sensor on the market. It features high sensitivity and signal to noise ratio, excellent stability against temperature changes and white light and enhanced RFI immunity.
The IRS-B210ST01-R1 series is suitable for person detection for security and proximity sensing applications, since it detects infrared at the wavelength emitted by the human body. Its small package size makes it suitable for consumer devices. Considering the surge in demand for energy saving devices, use of this sensor in household appliances such as lighting which switch off automatically when there is no-one in proximity, is anticipated.
The device features dual 0.85 x 1.2 mm electrodes with a field of vision of ±70° (horizontal) and ±50° (vertical). Its operating temperature range is -40 to +70°C and the device is driven by an supply voltage in the range of 2 to 15V.
Murata is a leading manufacturer of electronics components, modules, and devices.
