Rješavanje problema

Zašto očitanje senzora pokazuje 0 ili "Nema senzora"

1. Objekt mjerenja je vrlo blizu senzora, ali u mrtvom kutu senzora.
2. Ožičenje senzora je isključeno
3. Ne koristite ispravan dekoder

Abnormal readings The gap between multiple readings is too large or the gap between the readings and the actual value is too large.

1. Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
2. Does it change with temperature, temperature will affect its measurement
3. If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.downlink command: F1 01, AT command: AT+DDEBUG=1
4. Nakon ulaska u način otklanjanja pogrešaka, slat će 20 podataka odjednom, a vi nam možete poslati njegovu uzlaznu vezu na analizu

Njegov izvorni korisni teret bit će duži od ostalih podataka. Iako se analizira, vidi se da se radi o abnormalnim podacima.
Pošaljite nam podatke na provjeru.
