| 摘要 |
A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices. |

1. A method for monitoring and reporting environmental conditions within a building, comprising:
receiving, with a base unit configured to communicate using wireless communication and power-line communication, a smoke indication that indicates the existence of an emergency condition, the smoke indication being generated by, and communicated from, a sensor unit in response to the sensor unit detecting, with a smoke sensor, an amount of smoke within the building that is above a threshold value for the amount of smoke; in response to said receiving the smoke indication from the sensor unit, generating a notification of the emergency condition; and causing the notification of the emergency condition for the amount of smoke to be communicated, via the Internet, to a user device. |
