Tips: How to set up a temperature and humidity sensor?
The humidity sensor is not sealed. In order to protect the measurement accuracy and stability, the temperature and humidity sensor should not be used in acidic, alkaline and organic solvents. Environment with much dust shall also be avoided. To accurately reflect the humidity of the detected space, we should avoid placing the sensor in the corner which is close to the wall or the air is not well circulated. If the detected room is too large, several temperature and humidity sensors should be placed.
Some temperature and humidity sensors have higher requirements to the power supply, otherwise the measurement accuracy will be affected, or the sensors may interfere with each other and even don't work. Therefore, please provide suitable power supply with required accuracy according to requirements in the application.
When the temperature and humidity sensor needs long-distance signal transmission, we should pay attention to the attenuation of the signal. When the transmission distance is more than 200m, a temperature and humidity sensor with frequency output signal is recommended.
