A device that allows patients to recuperate and makes their families feel soothing and labor saving. It uses a temperature and humidity sensor, a human body infrared sensor, a finger pulse sensor, and a relay. The human body infrared sensor and the temperature and humidity sensor keep running and transmit the detected data to the mobile phone. If the temperature is up to standard and someone is detected, the required device will be turned on and the finger pulse sensor will detect the patient's heartbeat.
