NTC termistoridan foydalangan holda oddiy va arzon harorat sensori

Termistor o'z qarshiligini vaqt o'zgarishi bilan o'zgartiradi, bu xususiyat yordamida biz termistor haqida ko'proq bilib olamiz

1 -qadam: zarur komponentlar

Arduino uno (yoki) har qanday arduino ishlaydi

ba'zi o'tish simlari va non taxtasi

1 x 10 k qarshilik

1X NTC 10k termistor

2 -qadam: ulanishlar

(Er) ---- (10k-qarshilik) ------- | ------- (Termistor) ---- (+5v)

| Analog pin 0

3 -qadam: Farengeyt uchun kod

#qo'shing

er -xotin termistor (int RawADC) {er -xotin Harorat; Harorat = log (10000.0*((1024.0/RawADC-1)))); // = log (10000.0/(1024.0/RawADC-1)) // tortish konfiguratsiyasi uchun Temp = 1/(0.001129148 + (0.000234125 + (0.0000000876741 * Harorat * Harorat)) * Harorat); Harorat = Harorat - 273.15; // Kelvinni Celcius Temp ga aylantiring = (Temp * 9.0)/ 5.0 +32; // Selsiyni Farengeytga qaytish haroratiga aylantiring; }

void setup () {Serial.begin (115200); }

void loop () {Serial.println (int (Thermistor (analogRead (0))))); // Farengeyt kechikishini ko'rsatish (1000); }

4 -qadam: Selsiy uchun kod

#qo'shing

er -xotin termistor (int RawADC) {er -xotin Harorat; Harorat = log (10000.0*((1024.0/RawADC-1)))); // = log (10000.0/(1024.0/RawADC-1)) // tortish konfiguratsiyasi uchun Temp = 1/(0.001129148 + (0.000234125 + (0.0000000876741 * Harorat * Harorat)) * Harorat); Harorat = Harorat - 273.15; // Kelvinni Selsiyga qaytish haroratiga aylantiring; }

void setup () {Serial.begin (115200); }

void loop () {Serial.println (int (Thermistor (analogRead (0))))); // Farengeyt kechikishini ko'rsatish (1000); }

5 -qadam: Xulosa

barcha qadamlarni bajargandan so'ng, ketma -ket monitorni oching va 115200 -ga uzatishni sozlang, siz harorat ko'rsatkichlarini ko'rishingiz mumkin

Bunga lcd qo'shishingiz mumkin bo'lgan keyingi o'zgarishlar

rahmat:)

agar shubhangiz bo'lsa, so'rashdan tortinmang
