Q: Why is Temperature and Humidity Sensor important in some of the industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.
Q: How do I choose a suitable Temperature and Humidity Sensor?
A: There are a some important specifications you might need to consider when you choosing this product.
This includes:
* Accuracy
* Long-term stability
* Ability to recover from condensation
* Resistance to physical and chemical contaminants
*Interchangeability
* Repeatability
