The Storage Conditions And Precautions of Soil Humidity And Temperature Sensor
- Long-term exposure of the humidity sensor to high concentrations of chemical vapors will cause the sensor readings to drift. Therefore, during use, it is necessary to ensure that the sensor is away from high-concentration chemical solvents.
- Sensors that have been exposed to extreme operating conditions or chemical vapors can be restored to calibration as follows. Drying: Keep at 80°C and <5%RH for more than 10 hours; Rehydration: Keep at 20~30°C and >75%RH for 12 hours.
- The temperature and humidity sensor and circuit part inside the module have been treated with silicon rubber for protection, and are protected by a waterproof and breathable shell, which can improve its service life in high-humidity environments. However, it is still necessary to pay attention to avoid the sensor from being soaked in water, or used under high humidity and condensation conditions for a long time.
