The invention provides a vehicle-mounted life protection device with low cost and high safety. The vehicle-mounted life protection device comprises a sensing module, a vehicle window control module, a power supply control module and an alarm module. A single-chip microcomputer is connected with a GSM module through a serial communication circuit and further sends a rescue signal to a mobile phone of a vehicle owner through the GSM module. Once the device finds that people or animals are left in a vehicle, the device can lower down vehicle window glass automatically for preventing suffocation and turn on an alarm to give alarm and turn on hazard warning lamps. A pyroelectric infrared sensor and a sound sensor are both used to detect the vehicle interior condition, so that the detection accuracy is improved and the accidents of suffocation, injury and death of people or animals left in vehicles are prevented.
