The humidity sensor is not sealed. In order to protect the accuracy and stability of the measurement, it should be avoided in the atmosphere of acid, alkali and organic solvent. At the same time, avoid using in dusty environment. In order to correctly reflect the humidity of the measured space, the sensor should not be too close to the wall or placed in a dead corner without air circulation. If the room to be tested is too large, multiple sensors should be placed. Some humidity sensors need higher power supply, otherwise the measurement accuracy will be affected. Or the sensors may interfere with each other or even fail to work. Provide correct and accurate power supply according to technical requirements. When the sensor needs long-distance signal transmission, pay attention to the signal attenuation. When the transmission distance is more than 200m, it is recommended to select the humidity sensor with frequency output signal<br>
