Abstract

A room monitoring device designed and intended to detect a bowel movement (BM) of a person occupying the room, such as a baby or infant or an adult with special needs or in a care facility. The device tests the air for particular substances such as, but not limited to, methane and hydrogen sulfide. The test is performed multiple times per minute to reduce the chances of a false-positive detection. Once the device detects a positive BM, it alerts a user via Wi-Fi message, SMS text message, visual alerts (e.g., flashing lights), and/or audio alerts. This device may be paired with existing monitoring devices, such as a baby monitor with a remote camera.

Claims
