How to choose the right T＆H sensor for your project
IoT temperature and humidity sensors vary greatly in principle and structure. The first concern is how to choose a suitable temperature and humidity sensor based on the specific measurement purpose, object and environment. In addition, there are many factors to take into consideration, including sensor performance, transmission distance, application scenarios, and ease of installation. Here are some basic criteria for your reference.
Determine the sensor type: To carry out specific measurement tasks, priority should be given to the principle of the IoT temperature and humidity sensor, which depends on a number of factors. As for which working principle of the sensor is more suitable, it’s necessary to take the measured object and its application scenarios into consideration.
Frequency response characteristic: The frequency range that can be measured are determined by the temperature and humidity sensor’s frequency response characteristic. If the smart sensor has a high frequency response, then the measurable signal frequency range will be wide.
Linear range: The linear range of the smart temperature and humidity device refers to the range where the output is in proportion to the input. As long as the linear range of the smart device is wider, its measurement range is is larger, and a certain measurement accuracy is ensured. After determining the sensor type, it is necessary to determine whether the measurement range meets the requirements.
Sensitivity: In general, it is desirable that the sensitivity of smart sensors should be as high as possible in the linear range of the IoT temperature and humidity sensor. In the case of high sensor sensitivity, the output signal corresponds to the measurement variation value will be relatively large, which can help signal processing.
Stability: The ability of a temperature and humidity sensor to maintain its performance over a period of time is called stability. What affects the long-term stability of the smart temperature and humidity device is mainly its working environment, as well as the sensor structure. Therefore, proper measures can be set in place to reduce the environmental impact.
