In modern housing systems, sensors are an important part of the smart-home system. Sensors also play a vital role in ensuring safety. Hence, sensor elements are significantly included in modern reflected ceiling plans. Based on the housing type, the necessity of sensors varies, and so does their inclusion in the plan. Some common sensor elements are temperature sensors, humidity sensors, light sensors, voltage sensors, smoke detectors, current sensors, flow sensors, velocity sensors, vibration sensors, air quality sensors, etc. Some other sensor-related symbols that are included in a reflected ceiling plan are actuators, end switch, timer, level, the power connection, etc. These sensors and their associated elements are placed in a floor or space based on their area coverage and purpose.
