Abstract
A dryer vent monitor device includes a temperature sensor coupled to a dryer exhaust pipe to measure a temperature inside the dryer exhaust pipe. A differential air pressure sensor is coupled at an input connection between a dryer and the exhaust pipe and at an output connection between the dryer exhaust pipe and an outdoor vent. The differential air pressure sensor measures a differential air pressure between the input connection and the output connection. A transceiver communicates with a monitoring system registered with the dryer vent monitoring device. The dryer vent monitoring device compares both the temperature and the differential air pressure with a preset threshold, determines that at least one of the temperature and the differential air pressure exceed the preset threshold, and generates an alert signal in response to determining that at least one of the temperature and the differential air pressure exceed the preset threshold.
