usage of temperature sensor (lm 35)

used element:

1. Ardinuo uno
2. lm 35
3. lcd
4. pot
5. Bluetooth module
6. 2 buzzers

concept :

• Our application is the Dry Sterilizer which used for medical supplies, medical devices and others to kill bacteria using high pressure and temperature . it uses at 105-150 °C, under a high pressure. • 6 min: 190 °C • 30 min: 180 °C • 60 min: 170 °C • 120 min: 160 °C • 150 min: 150 °C • Overnight: 105–135 °C

Why LM35 temperature sensor ?

• Its range is -55 to 150 which contains the range of the steam sterilizer, low cost, greater accuracy (-+1), The output voltage can easily be interpreted to obtain a temperature reading in Celsius.
