With advancement of technology at present health monitoring is one of the most emerging fields. Recently Internet of things is used in various applications like remote monitoring of parameters; control the process far away from the plant etc. In our work we used internet of things to design a health monitoring system using Arduino and several sensor network. This system will monitor the body temperature, environmental temperature, humidity, heart rate and fall detection of the patients. The measured value will be communicated to the thingspeak cloud platform. The thingspeak will read the values and send an alert message to the responsible person in the family and also to the respective doctors to do the immediate aid for the patients under abnormal conditions.
