Nov yog qhov me me Arduino module rau ntsuas TrueRMS qhov hluav taws xob. Lub ntsuas ntsuas qhia qhov rms voltage hauv mV nrog tus lej thiab qhov sib piv qib sib piv.

Tus qauv yog npaj ua "tsim hauv" module rau saib xyuas lub teeb liab.

Kev tsim qauv yog tsim nrog cov kab hluav taws xob nkag mus rau theem teeb liab raug rau Arduino.

Qhov no yog tsim los ntawm qib av virtual ntawm 2V5. Qhov no xav tau rau kev ntsuas analog thiab ntsuas lub teeb liab raug.

Lub op-amp kuj txhim kho cov tswv yim impedance. Qhov nce tag nrho yog 0dB.
