Low Power Sensor System

A method for controlling power to a device, comprising:

• sensing a condition with a sensor-controlled switch causing said switch to be reconfigured from an open configuration to a closed configuration;
• keeping said sensor-controlled switch in said closed configuration while enabling a radio and performing a task;
• entering a low power state wherein said radio is disabled;
• remaining in said low power state and preventing said sensor-controlled switch from reconfiguring from a closed configuration to an open configuration or from an open configuration to a closed configuration for a period of time;
• and
• reconfiguring said sensor-controlled switch to be in said open configuration if it is not already in said open configuration.

A low power apparatus comprising:

• a sensor-controlled switch that is reconfigurable between an open configuration and a closed configuration;
• said sensor-controlled switch coupled to a power source;
• said sensor-controlled switch configured to be unresponsive to conditions sensed by said sensor-controlled switch when said sensor-controlled switch is in said closed configuration;
• said sensor-controlled switch allowing power to flow from said power source to a device when said sensor-controlled switch is in said closed configuration;
• a delay function configured to determine a period of time during which said device is kept in a low power state after a task has been performed;
• a low power radio that is disabled during said low power state and when sensor-controlled switch is in said opened configuration;
• and
• said sensor-controlled switch configured to be responsive to conditions sensed by said sensor-controlled switch after said period of time and when said sensor-controlled switch is in said open configuration.
