Abstract

We have developed a sensor that consists of a single-pixel thermopile and a signal-processing unit in a single package, which is able to detect people in a range of up to 3 meters. The device can work without any optical system such as a multifocal Fresnel lens. In order to suppress unwanted false triggers an internal background subtraction algorithm is applied. Besides motion and presence detection, also temperature measurement and monitoring features were implemented in the compact SMD package. The combination of an interrupt feature and a very low power consumption of only 50 μW make this device ideal for space- onstraint consumer devices.
