A remote monitoring device is connected to a rubber strap and contains: a controller, a global system for mobile communication (GSM), a global positioning system (GPS), a Wi-Fi & blue tooth, and a near field communication (NFC). The controller includes a microprocessor, a blood pressure sensing unit, a heartbeat sensing unit, a temperature sensing unit, and a wireless signal transmitting unit. The blood pressure sensing unit is configured to sense blood pressure of a care-receiving person, the heartbeat sensing unit is used to sense heart beating of the care-receiving person, the temperature sensing unit is employed to sense a temperature of the care-receiving person, and the microprocessor receives, compares, calculates and sends sensed signals of the blood pressure, the heart beating, and the temperature. The GSM, the GPS and the Wi-Fi & blue tooth are joined with the controller, respectively.
