A sensor unit includes at least one sensor configured to measure an ambient condition. The controller can be configured to receive instructions, to report a notice level when the controller determines that data measured by the at least one sensor fails a report threshold test corresponding to a report threshold value. The controller can also be configured to obtain a plurality of calibration measurements from the at least one sensor during a calibration period and to adjust the threshold based on the calibration measurements. The controller can be configured to compute a first threshold level corresponding to background noise and a second threshold level corresponding to sensor noise, and to compute the report threshold value from the second threshold. In one embodiment, the sensor unit adjusts one or more of the thresholds based on ambient temperature.

What is claimed is: 1. A sensor unit, comprising: at least one sensor configured to measure an ambient condition; and a controller, said controller configured to receive instructions, said controller further configured to report a notice level when said controller determines that data measured by said at least one sensor fails a report threshold test corresponding to a report threshold value, said controller configured to obtain a plurality of calibration measurements from said at least one sensor during a calibration period and to adjust said threshold based on said calibration measurements, said sensor unit further configured to adjust said threshold based on ambient temperature, said controller configured to compute a first threshold level corresponding to background noise and a second threshold level corresponding to sensor noise, said controller configured to compute said report threshold value from said second threshold. 2. The sensor unit of claim 1, wherein said at least one sensor comprises a smoke sensor. 3. The sensor unit of claim 1, said controller configured to receive said report threshold value from a central control system. 4. The sensor unit of claim 1, said controller configured to receive said report threshold value from an external source. 5. The sensor unit of claim 1, wherein said at least one sensor comprises a water-temperature sensor. 6. The sensor unit of claim 1, wherein said at least one sensor comprises a moisture sensor. 7. The sensor unit of claim 1, wherein said at least one sensor comprises a humidity sensor. 8. The sensor unit of claim 1, wherein said at least one sensor comprises a carbon monoxide sensor. 9. The sensor unit of claim 1, wherein said at least one sensor comprises a flammable gas sensor. 10. The sensor unit of claim 1, wherein said at least one sensor comprises a door-open sensor. 11.

The sensor unit of claim 1, wherein said at least one sensor comprises a power-failure sensor. 14. The sensor unit of claim 1, wherein said report threshold value is computed, at least in part, as an average of a plurality of sensor data values. 15. The sensor unit of claim 1, wherein said report threshold value is computed, at least in part, as a weighted average of a plurality of sensor data values. 16. The sensor unit of claim 1, wherein said alert level is computed according to how far a sensor reading has risen above said report threshold value. 17. The sensor unit of claim 1, wherein said alert level is computed as a function of how far and how rapidly sensor readings have risen above said threshold value. 18. The sensor unit of claim 1, wherein said alert level is computed as a function of how many sensor readings have been measured above said threshold value. 19. The sensor unit of claim 1, wherein said alert level is computed as a function of what percentage of recent sensor readings have been measured above said threshold value. 20. The sensor unit of claim 1, wherein a threshold value of an optical smoke sensor is computed using, at least in part, temperature information from a temperature sensor. 21. The sensor unit of claim 1, said sensor unit further comprising a fan configured to improve air exchange between a sensor chamber and ambient air. 22. The sensor unit of claim 21, wherein said fan is provided to said controller, said controller configured to operate said fan during one or more measurement periods. 23. The sensor unit of claim 21, wherein said fan is provided to said controller, said controller configured to operate said fan prior to one or more measurement periods. 24. The sensor unit of claim 21, wherein said controller reports a diagnostic error at least when said second threshold does not exceed said first threshold. 25. The sensor unit of claim 21, wherein said controller reports a diagnostic error at least when said second threshold does not exceed said first threshold. 26. The sensor unit of claim 21, wherein said controller measures said first threshold and said second threshold in response to a command. 27. The sensor unit of claim 21, wherein said controller measures said first threshold and said second threshold at power-up.
