The use of sensors in the food industry has increased considerably in recent years. Sensors are electronic devices that can measure various parameters such as temperature, humidity, pressure and pH value. This data is of great importance to food manufacturers as it helps them to ensure the quality and safety of their products, and one example of the use of sensors is the monitoring of temperature during the manufacturing process. High temperatures can lead to certain bacteria and microorganisms being killed, which is crucial for the shelf life of food. Sensors can continuously measure the temperature and raise the alarm immediately in the event of deviations so that appropriate measures can be taken. Excessive humidity can lead to mold growth and affect the quality of the food. Sensors can measure the moisture and automatically regulate the humidity if necessary. pH value is also very important, as it provides information about the acidity of a food. An incorrect pH value can lead to faster spoilage. Sensors can accurately measure the pH value and thus ensure that products have the correct acidity, and the use of sensors in the food industry helps to improve product quality and safety. By continuously monitoring various parameters, potential problems can be detected and rectified at an early stage. This helps manufacturers to keep their products competitive and gain the trust of consumers.
