The invention relates to an alarm for preventing life entities from being left in a car. The alarm includes a current sensor, a pressure sensor, a central processor, an infrared inductor, a buzzer, a Bluetooth communication module, a storage battery and a mobile phone client; the current sensor transmits engine flameout signals to the central processer; the pressure sensor detects car door locking states and transmits detection signals to the central processor; after receiving the car engine flameout signals and car door locked signals, the central processor triggers the infrared inductor, so that the infrared inductor scans the interior of the car and transmits scanning result signals to the central processor; and the central processor analyzes and processes the scanning results, and then, outputs alarm signals to the buzzer and mobile phone client through the Bluetooth communication module, so that the buzzer can buzz, or after the mobile phone client of the owner of the car confirms the alarm information, and the buzzer stops working. With the alarm of the invention adopted, the detection device is triggered after the parking of a driver is confirmed, and therefore, children or other life entities can be prevented from being locked in the car, and sad tragedies can be avoided.
