Voltage at pin in milliVolts = (reading from ADC) * (3300/1024)
Centigrade temperature = [(analog voltage in mV) – 0,5] / 0,01

Voltage at pin in milliVolts = (reading from ADC) * (5000/1024)
Ushbu formula 0-1023 bo`lgan qiymatni 0-5000mV (= 5V) kuchlanish
qiymatiga aylantirib beradi.
Agar siz Arduino da 3.3V portni ishlatadigan bo`lsangiz, siz quyidagi
formuladan foydalanishingiz mumkin:
Voltage at pin in milliVolts = (reading from ADC) * (3300/1024)
Ushbu formula 0-1023 bo`lgan sonli qiymatnin 0-3300mV (= 3.3V) bo`lgan
kuchlanish qiymatiga aylantirib beradi.
Keyinchalik, millivoltni temperaturaga aylantirish kerak, bunda quyidagi
formuladan foydalanamiz:
Centigrade temperature = [(analog voltage in mV) – 0,5] / 0,01
1.
temp = analogRead(2)*5/1024.0; - analog kirish sonli qiymat signalini
kuchlanish signaliga aylantiradi.
2.
temp = temp - 0.5; va temp = temp / 0.01; - millivolt qiymatini
temperatura qiymatiga aylantirib beradi.

Ishni bajarish tartibi
1.Talabalar o`qituvchi tomonidan berilgan ma`lumotlar asosida “Arduino
Uno” yordamida atrof-muhit temperaturasini o`lchaydi.
2.Talaba bajargan ishlari bo`yicha o`qituvchiga yozma hisobot tayyorlab
topshiradi.
