++DDS75-LB is not suitable to be used in condensation environment. Condensation on the DDS75-LB probe will affect the reading and always got 0.

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

++== 7.3  Why does the sensor reading show 0 or "No sensor" ==
++
++
++~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
++
++2. Sensor wiring is disconnected
++
++3. Not using the correct decoder
++
++
++== 5.4  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: (% style="color:blue" %)**F1 01**(%%), AT command: (% style="color:blue" %)**AT+DDEBUG=1**
