Temperature monitoring systems are tools used to measure and track temperature in various environments. These systems can be found in homes, laboratories, and industrial settings, ensuring that temperatures remain within safe or optimal ranges. They often include sensors, displays, and alarms to alert users when temperatures exceed or drop below set limits. These systems can be manual or automated, with some connected to the internet for remote monitoring. Common applications include food storage, pharmaceuticals, and climate control in buildings. By maintaining proper temperatures, these systems help prevent spoilage, ensure safety, and improve efficiency in various processes.
