Occupancy indicator device

An occupancy indicator device to indicate occupancy of a bathroom, the occupancy indicator device comprising:

• a control unit disposed inside the bathroom, comprising:
• a motion sensor configured to detect motion of a bathroom door;
• an inertial measurement unit (IMU) configured to monitor a position of the bathroom door;
• an occupancy sensor configured to detect movement of an object in the bathroom;
• an ambient light sensor configured to determine a status of an ambient light of the bathroom;
• and
• a processor configured to:
• execute a machine learning algorithm using data captured by the motion sensor, the IMU and the ambient light sensor to determine an occupancy status of the bathroom, and
• generate data pertaining to a bathroom occupancy, duration of each usage, and when the bathroom was serviced;
• and
• a light indicator system disposed outside the bathroom door on a wall and disposed in wireless communication with the control unit, wherein a color of the light indicator system is responsive to a combination of sensor inputs feeding the machine learning algorithm.

A computer implemented method to indicate occupancy of a stall, comprising:

• detecting an occupancy status of the stall using a motion sensor;
• monitoring a position of a door of the stall using an inertial measurement unit (IMU);
• determining a status of an ambient light of the stall using an ambient light sensor;
• executing by a processor, a machine learning algorithm using data captured by the motion sensor, the inertial measurement unit and the ambient light sensor;
• determining an occupancy status of the stall and generating data regarding a stall occupancy, duration of each usage and when the stall was serviced;
• and
• indicating occupancy of the stall via a light indicator system disposed outside of the door, and communicatively coupled to a control unit, wherein a color of the light indicator system is responsive to a combination of one or more sensor inputs feeding the machine learning algorithm.
