ABSTRACT
The Short Message System (SMS) of a standard mobile phone can be used for much more than just exchanging cryptic message. This application finds a humble mobile working for controlling external equipments. The SMS service provides by the service providers are comparatively low cost. Hence the system is highly efficient and low-cost.
Mobile phones have become a widespread means of communication. It becomes a part of everyday life with ever more people enjoying the service and extra freedom they provide. It works on the basis of Global System for Mobile Communication (GSM). A subscriber from any systems can access telecommunication services by using a Subscriber Identity Module (SIM) card in a handset suitable for the network on the visited system The Short Message Service allows text messages to be sent and received to and from mobile telephones. The text can comprise words or numbers or an alphanumeric combination. Because Simple person - to - person messaging is such an important component of total SMS traffic volumes, anything that simplifies message generation as well as extended utility of the SMS being sent is an important enabler of Short Message Service.
The purpose of this project is to measure the heartbeat and send the heart rate value to the remote location (can be a doctor) as SMS message. GSM based heart beat monitoring and display system is a portable and a best replacement for the old model stethoscope, which is less efficient. It is a combination of a High Power LED and LDR sensor based heart rate monitor interfaced with a GSM module to transmit the heart rate of the patient to a remote location.
The functioning of this device is based on the truth that the blood circulates for every heartbeat that can be sensed by using a circuit formed by the combination of a LDR and LED. Depending upon the rate of circulation of blood the heart beat rate per minute is calculated. This calculated value is communicated to remote person through a GSM modem interfaced to it.
