1. Mounting Location: The mounting location is crucial to the measurement accuracy of a temperature and humidity sensor. In indoor environments, avoid installing the sensor near heat sources, cold sources, or air vents. Heat sources such as radiators and air conditioner vents can be significantly hotter than the surrounding environment, resulting in inaccurate measurement results. Strong air flow near air vents can also cause the sensor to inaccurately reflect actual temperature and humidity conditions. In outdoor environments, choose a location that represents the ambient temperature and humidity, avoiding direct sunlight and rain.
2. Mounting Method: Various mounting methods are available depending on the application scenario and sensor type. Small temperature and humidity sensors can be fixed in place using adhesive or magnetic attachment. Larger sensors may require screws or brackets. During installation, ensure the sensor is securely mounted to prevent vibration or movement that may affect measurement accuracy.
3. Connection and Configuration: After installing the temperature and humidity sensor, you must perform proper connections and configuration. If the sensor outputs an analog signal, it needs to be connected to the corresponding analog acquisition module and parameter settings, such as the measurement range and acquisition frequency, must be configured according to the module's requirements. For sensors with digital output, connection and configuration must be performed according to the communication protocol requirements, such as setting the communication interface type (such as I2C, SPI, etc.) and baud rate. During the connection process, ensure that the wiring is correct to avoid problems such as short circuits or open circuits.
4. Calibration and Maintenance: To ensure the measurement accuracy of temperature and humidity sensors, regular calibration is essential. Calibration can be performed using professional calibration equipment and according to specific calibration procedures. Sensors should also be regularly maintained to remove dust and dirt from the sensor surface to prevent performance degradation. If any deviation in sensor measurement results is observed during long-term use, prompt inspection and repair should be performed.
