Inadvertent operations in touchless lavatory

A lavatory sensor control system, comprising:

• one or more sensors, each of the one or more sensors being configured to transmit sensor data;
• one or more motors, each motor of the one or more motors connected to one of the one or more sensors;
• and
• a central controller configured to communicate with the one or more sensors and the one or more motors, wherein the central controller receives the sensor data from the one or more sensors, processes the sensor data, and transmits a message to activate one of the one or more motors, wherein the sensor data includes an ambient light measurement and wherein the central controller is further configured to:
• identify a first group of sensors of one or more groups of sensors of the one or more sensors to which a first sensor belongs;
• request and then receive the ambient light measurement from each of the one or more sensors;
• compute an average ambient light value of all sensors in the one or more sensors based on the ambient light measurement from each sensor of the one or more sensors;
• compare the ambient light measurement of the first sensor to the average ambient light value of all sensors in the one or more sensors;
• determine that the ambient light measurement of the first sensor is less than the average ambient light value of all sensors;
• determine that a first trigger event from the first sensor of the one or more groups of sensors to which the first sensor belongs is valid based on determining that the ambient light measurement of the first sensor being less than the average ambient light value of all sensors;
• and
• perform an action in response to the determining that the first trigger event is valid, wherein the action is transmitting the message to a first motor of the one or more motors, the first motor being associated with the first sensor.

A method, comprising:

• determining, by a central controller, a first trigger event from a first sensor of a plurality of sensors;
• identifying, by the central controller, a group to which the first sensor belongs;
• requesting and then receiving, by the central controller, an ambient light measurement from each of the plurality of sensors, including a first ambient light measurement from the first sensor;
• computing, by the central controller, an average ambient light value of all sensors based on the ambient light measurement from each of the plurality of sensors;
• comparing, by the central controller, the first ambient light measurement to the average ambient light value of all sensors;
• determining, by the central controller, that the ambient light measurement of the first sensor is less than the average ambient light value of all sensors;
• determining, by the central controller, that the first trigger event is valid based on determining that the ambient light measurement of the first sensor being less than the average ambient light value of all sensors;
• and
• activating, by the central controller, a motor in response to the first trigger event being valid.
