The pulse sensor can also detect body temperature. Put this lm35 sensor on your arm and cover it with a cloth and enjoy measuring your body temperature.
Project 003 Arduino Lm35 Temperature Sensor Project
Body temperature measurement arduino. The arduino can read input from 0 5v. External with partial contact in air 91 may as high as youll see. Dht22 this low cost sensor also measures humidity. It has a serial digital output and can easily be used with most microcontrollers. As everyone knows the normal body temp is 98f its 986 to be exact. 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 output voltage rises by 10mv for every 1 degree celsius rise in temperature. The arduino stores this as a 10bit number 0 1023. The arduino code also uses a function to provide an led fading effect on every beat. The five sensors we will look at are as follows. Now as we have made a digital thermometer using arduino. The operating temperature range of lm 35 is from 55 c to 150 c.
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. Sensor and will show the readings in bpm beat. But thats the internal temperature. Today we will look at five different sensors you can use to measure temperature with an arduino. H eart beat and body temperature monitoring using arduino will detect the heart beat using the pulse sensor and body temperature using lm 35 sensor. The lm 35 is used to detect the surrounding temperature here.
