Humidity sensor is non-sealing. In

Humidity sensor is non-sealing. In order to protect the accuracy and stability of the measurement, it should be avoided in the atmosphere of acid, alkaline and organic solvents.Also avoid the use in the dust environment.In order to correctly reflect the humidity of the space to be measured, the sensor should also be avoided by placing it too close to the wall or in a dead corner where there is no air circulation.If the room being tested is too large, multiple sensors should be placed.Some humidity sensors have high requirements on the power supply, otherwise the measurement accuracy will be affected.Or the sensors could interfere with each other or even fail to work.Suitable and accurate power supply should be provided according to the technical requirements.When the sensor needs to carry on the long-distance signal transmission, we should pay attention to the signal attenuation problem.When the transmission distance is more than 200m, it is recommended to choose the humidity sensor with frequency output signal.
