Odpravljanje težav

Zakaj odčitek senzorja kaže 0 ali "Ni senzorja"

1. Merilni objekt je zelo blizu senzorja, vendar v mrtvem kotu senzorja.
2. Ožičenje senzorja je odklopljeno
3. Ne uporabljate pravilnega dekoderja

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
