Wireless sensor unit communication triggering and management
First Claim
1. A wireless ambient sensor unit, comprising:
- a wireless transceiver;
a sensor configured to measure quantitative data about an ambient condition;
a controller in communication with the wireless transceiver and the sensor, the controller configured to;
compare the quantitative data measured about the ambient condition to a stored threshold value while the wireless ambient sensor unit is in a low-power mode;
exit the low-power mode in response to the comparison of the quantitative data with the stored threshold value; and
in response to the exit of the low-power mode, transmit the quantitative data measured about the ambient condition as one or more messages, using the wireless transceiver, the quantitative data being transmitted while the wireless ambient sensor unit is out of the low-power mode and each message includes an address that identifies the wireless ambient sensor unit, a checksum, and an authenticity portion for use in verifying an authenticity of the message.

Abstract
Various embodiments of wireless ambient sensor unit are presented. The sensor unit may include a wireless transceiver configured to transmit sensor data and to receive instructions. The sensor unit may include a sensor configured to measure an ambient condition. The sensor unit may include a controller in communication with the wireless transceiver and the sensor. The controller may be configured to compare data measured about the ambient condition to a stored threshold while the wireless ambient sensor unit is functioning in a low-power mode. The controller may be configured to exit the low-power mode in response to the comparison of the data with the stored threshold. The controller may be configured to cause the data measured about the ambient condition to be transmitted by the wireless transceiver as one or more messages in response to the comparison to the stored threshold.
