Factors to Consider When Buy a WIFI Thermometer

The range of the temperature and humidity sensor

Each industry has different measurement ranges for temperature and humidity because of the different environments and processes used. Generally speaking, meteorological or scientific research departments have relatively extensive requirements for temperature and humidity ranges. If the above two fields are not involved, you can choose a universal WIFI temperature and humidity sensor, of course, you can also propose the measurement range for the temperature and humidity sensor manufacturer to customize according to your own needs.

Temperature and humidity sensor accuracy

Measurement accuracy is also an important indicator of wireless thermometers and hygrometers. You can choose the appropriate accuracy according to your own field and needs. For example, industries such as hospitals and refrigerated transportation have relatively high accuracy in temperature and humidity, while factories and manufacturing industries may not require so high measurement accuracy. Of course, every time the measurement accuracy is increased by one percentage point, its requirements and grades will rise significantly, and the prices will also be different.

The influence of time drift and temperature drift

Because the WIFI temperature and humidity sensor need to contact the water vapor in the atmosphere, the device will not be sealed. This causes its life and stability to vary depending on the environment, resulting in time drift, which is also a floating life. In general, the service life of a temperature and humidity sensor is 1 to 2 years. Temperature drift refers to whether the sensor can work normally and whether the measurement data is normally in the temperature change range of the application, which is also a very important indicator.

Determine the appearance of the device

For example, if a screen display is required, the power consumption will generally be relatively large if a screen display is required. Without the need for screen display, the power consumption is small and the battery lasts for a long time.


When choosing a wireless temperature and humidity timer, you should choose a cost-effective product, rather than simply choosing a low-priced product. If you only pay attention to the price, you will encounter the problems of short life, low accuracy, and poor quality during use, which will also greatly increase the cost.

Quality and reliability

The quality of the product should be judged by examining the manufacturer’s on-site standards and quality appraisal; the reliability of the product can also be determined by comprehensive factors such as the temperature and humidity sensor manufacturer’s reputation, brand, and reputation.


When choosing a transmitter, you should determine which product to choose based on your actual situation and use environment. Need to fully consider adaptability factors.


Temperature and humidity sensors need to be regularly inspected, updated, replaced and repaired.
