660 -
661 -
662 -It is due to channel mapping. Please see below link:  [[Frequency band>>doc:Main.LoRaWAN Communication Debug.WebHome||anchor="H2.NoticeofUS9152FCN4702FAU915Frequencyband"]]

671 -== 7.3  Why does the sensor reading show 0 or "No sensor" ==
672 -
673 -
674 -~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
675 -
676 -2. Sensor wiring is disconnected
677 -
678 -3. Not using the correct decoder

681 -== 7.4  Abnormal readings The gap between multiple readings is too large or the gap between the readings and the actual value is too large ==
682 -
683 -
684 -1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
685 -
686 -2) Does it change with temperature, temperature will affect its measurement
687 -
688 -3) If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.
