Which of the following sensors would typically be used in a bathroom or kitchen area for continuous monitoring?

The appropriate choice for continuous monitoring in a bathroom or kitchen area is a heat detector. This type of sensor is specifically designed to respond to significant temperature changes associated with fires, making it ideal for environments that may experience high humidity or steam, such as bathrooms and kitchens.

In these areas, traditional smoke detectors may produce false alarms due to the presence of steam or cooking smoke. Heat detectors function by sensing rapid increases in temperature, thus providing reliable functionality without the risk of false positives caused by everyday activities in these spaces.

While other sensors like motion detectors, glassbreak detectors, and water leak detectors have their own applications, they are not primarily focused on fire detection in high-humidity areas. Motion detectors are more suited for security applications, glassbreak sensors are used for windows and doors, and water leak detectors specifically address potential water damage rather than fire risks. Hence, the heat detector stands out as the most effective choice for continuous monitoring in such environments.
