Abstract
A method, apparatus and program product for differential particle detection in electronic devices is provided. A first particulate sensor is positioned in proximity to an air intake of the electronic device. A second particulate sensor is positioned in proximity to the air exhaust of the device. A comparator compares the particulate concentrations detected by the first and second particulate sensors. Differential particle detection between the air intake and air exhaust of an electronic device enables early detection of potential fire conditions existing within the electronic device.
