The quality of food is impacted by temperature and humidity in different ways. Food consistency can change due to temperature, which may encourage the growth of potentially harmful microbes. Nutrition can also be negatively impacted by uncontrolled humidity. Food must be handled safely and kept in locations that are strictly regulated. The light, humidity, and temperature are continuously measured by the WS1-Pro. On an LCD panel, every piece of data is displayed. The best thing about this device is that it is waterproof and works on batteries.
