In the food storage industry, accurate control of temperature and humidity is crucial. The temperature and humidity field inspection instrument can monitor the temperature and humidity data in different areas of the warehouse in real time. By arranging sensors in every corner of the warehouse, the inspection instrument can quickly collect data to ensure that food is in a suitable storage environment. For example, for dry goods food, excessive humidity may lead to mildew and deterioration, and the taste and quality of some foods will also be affected in a low-temperature environment. The temperature and humidity field inspection instrument can accurately locate the areas with abnormal temperature and humidity and issue alarms in time, allowing managers to take corresponding measures, such as starting ventilation equipment or adjusting the air conditioning system, effectively extending the shelf life of food and ensuring food safety.
