Put this lm35 sensor on your arm and cover it with a cloth and enjoy measuring your body temperature. The method that i am going to use now can be used to measure temperature from 2 degree celsius to the maximum temperature that your lm35 can measure.

Body temperature measurement arduino. The five sensors we will look at are as follows. The arduino code also uses a function to provide an led fading effect on every beat. Dht22 this low cost sensor also measures humidity. These devices are extremely used to measure the body temperature of sick people as the temperature is one of the first factors that change in the human body when there is an abnormality or disease. Now as we have made a digital thermometer using arduino. There are several ways to read temperature with an arduino.
The temperature sensor for arduino is a fundamental element when we want to measure the temperature of a processor of the human body. A few of these include. The pulse sensor can also detect body temperature. The arduino stores this as a 10bit number 0 1023. To display the ferhanite temperature on the serial monitor also we have used a formula to convert this temperature to ferhanite and than displayed it on screen. The operating temperature range of lm 35 is from 55 c to 150 c.
It has a serial digital output and can easily be used with most microcontrollers. Today we will look at five different sensors you can use to measure temperature with an arduino. The temperature sensor with arduino must be in contact or close to receive and measure the heat level. The lm 35 is used to detect the surrounding temperature here. The output voltage rises by 10mv for every 1 degree celsius rise in temperature. I2c or serial sensors there are advanced sensor modules that often can measure barometric pressure temperature humidity and other conditions all in one package.
The arduino can read input from 0 5v. Thats how thermometers work.
