An approach is provided for remote healthy caring and monitoring through data transmission and processing. A biological monitoring device comprises a biological sensor, a motion detector, a warning module, a transmitting module and a controller. The biological sensor acquires a biological data from a person. The motion detector senses a variation of acceleration and a variation of angle to acquire a physical condition data. The transmitting module transmits the biological data and the physical condition data to a terminal device. The controller calculates the biological data and the physical condition data based on a predetermined rule, and sends a control signal to trigger a warning module or the transmitting module according to a calculating result. The warning module is configured to send a noticeable signal to inform the person. Therefore, the monitoring range is dynamically adjusted based on the biological and physical of the person.
