1. An electronic device configured as a base unit for monitoring and reporting environmental conditions, the electronic device comprising:
- one or more transceivers to communicate using wireless communication; and
a controller operatively coupled to the one or more transceivers and configured to;
receive, from a sensor unit, at least measured signal strength of wireless signals received by the sensor unit;
select routing paths for routing packets based on an evaluation of the received signal strength measurements;
based on the selection of the routing paths, send instructions to a wireless repeater unit to add an identifier of the sensor unit to a database included in the wireless repeater unit to configure the wireless repeater unit to route communication traffic for the sensor unit through the wireless repeater unit;
receive an encrypted packet that includes an indication of the existence of an emergency condition, the encrypted packet being generated by, and communicated using the wireless communication and over a selected routing path from, the sensor unit in response to the sensor unit detecting that an environmental condition is above a threshold value, the encrypted packet including an address portion that comprises a first code, a second code, and a checksum;
in response to the reception of the encrypted packet from the sensor unit, generate a notification of the emergency condition; and
cause, via the wireless communication, the notification of the emergency condition, to be communicated via the Internet, to a user device.

Abstract
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.

9. A system for monitoring and reporting environmental conditions within a building, the system comprising:
-
a sensor unit configured to; measure signal strength of wireless signals received by the sensor unit from a base unit and from one or more wireless repeater units; transmit the signal strength measurements of the base unit; sense an environmental condition; and the base unit configured to; receive, from the sensor unit, at least measured signal strength of wireless signals received by the sensor unit; select routing paths for routing packets based on an evaluation of the received signal strength measurements; based on the selection of the routing paths, send instructions to a wireless repeater unit to add an identifier of the sensor unit to a database included in the wireless repeater unit to configure the wireless repeater unit to route communication traffic for the sensor unit through the wireless repeater unit; receive, via wireless communication and over a selected routing path, an encrypted packet that includes an indication of the existence of an emergency condition, the encrypted packet being generated by, and communicated using the wireless communication from, the sensor unit in response to the sensor unit detecting that an environmental condition is above a threshold value, the encrypted packet including an address portion that comprises a first code, a second code, and a checksum; in response to the reception of the encrypted packet from the sensor unit, generate a notification of the emergency condition; and cause, via the wireless communication, the notification of the emergency condition, to be communicated via the Internet, to a user device. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for monitoring and reporting environmental conditions within a building, comprising:
-
receiving, at a base unit, at least measured signal strength of wireless signals received by a sensor unit; selecting routing paths for routing packets based on an evaluation of the received signal strength measurements; based on the selecting the routing paths, sending instructions to a wireless repeater unit to add an identifier of the sensor unit to a database included in the wireless repeater unit to configure the wireless repeater unit to route communication traffic for the sensor unit through the wireless repeater unit; receiving, at the base unit, an encrypted packet that includes an indication of the existence of an emergency condition, the encrypted packet being generated by, and communicated using wireless communication and over a selected routing path from, the sensor unit in response to the sensor unit detecting that an environmental condition is above a threshold value, the encrypted packet including an address portion that comprises a first code, a second code, and a checksum; in response to the receiving the encrypted packet from the sensor unit, generating a notification of the emergency condition; and causing, via the wireless communication, the notification of the emergency condition, to be communicated via the Internet, to a user device. - View Dependent Claims (17, 18, 19, 20)
