Iyerekana ry’ubushyuhe mu ishuri

Huza icyuma cya MCP9808 gipima ubushyuhe n'icyerekana cy'imibare 4 ku murongo rusange wa I2C. Soma ubushyuhe muri dogere Selisiyasi maze ubyerekane kuri display.

Iyerekana ry’ubushyuhe mu ishuri

Intego

Huza MCP9808 (0x18) na display (0x70) kuri 5V, GND, SCL na SDA.
Tegura uruziga rusoma ubushyuhe muri °C rukabwandika kuri display.
Reba nibura inshuro 3 display ihinduka ihuje n'ubushyuhe.

Ibyitezwe

Icyerekana cy'imibare 4 cyaka kikerekana ubushyuhe muri dogere Selisiyasi (urugero ' 24.5'), kigahinduka uko ubushyuhe buhindutse.

Ibyo iri gerageza rishobora n’ibyo ridashobora kwerekana

Icyitegererezo cyo kwiga: ubushyuhe bwigana muri °C (intambwe ya 0.5 °C). Ni icyo kwerekana gusa, si icyuma gikonjesha cyangwa gishyushya ishuri.

Hitamo uko utangira

Tangira ubusa ushyireho buri gikoresho ubwawe, cyangwa ufungure intangiriro: ikibaho, breadboard, résistance, LED na porogaramu yo gucana idahujwe. Uracyashyira ibikoresho mu myobo, ukora buri muhuza kandi uhuza amabuye.
