Temperature Sensor
The amount of heat observes is sensed using sensor called temperature sensor. Mostly, there are two types of temperature sensor contact and noncontact. Examples of contact sensor are thermocouple, RTD, thermistor, thermometer, diodes, etc. And examples of noncontact sensors are radiation and pyrometers. The output of temperature sensor is smaller in amplitude as well as low signal power so amplifier is used to amplify weak signal.
We have used here LM35 series temperature sensor. LM35 series sensor is an integrated circuit whose output is linearly proportional to centigrade or Celsius temperature. Because of we get directly output of LM35 series sensor in centigrade it becomes its advantage as compared to linear temperature …show more content…

There are many disadvantages of this traditional Electrocardiography electrodes are metal allergy can causes skin irritation, short term use, too much expensive and single use electrodes to overcome these disadvantages non-contact Electrocardiography sensor are used here named as EPIC (Electric potential Integrated Circuit) sensor. EPIC sensor is discovered in UK which has specialty of sensing without any physical contact with body. EPIC sensor collects the electrical signal which generated while pumping action of heart without any direct physical contact with body. EPIC sensors collect Heart activity in the form of electrical signal which has amplitude about 2mV for length of 20ms with bandwidth …show more content…

It is also called as data selector. In another word multiplexer has multiple input and single output. Mainly, Multiplexer used increase amount of data to be transfer within certain amount of time and bandwidth. Also can be used to implement Boolean functions of multiple variables.The schematic symbol for a multiplexer is an isosceles trapezoid with the longer parallel side containing the input pins and the short parallel side containing the output
