Abstract: Disclosed is a sensor for detecting the proximity of smart devices previously connected to the sensor using the IEEE 802.11 protocols. Importantly, the sensor does not operate using a Bluetooth® connection, which would require the smart devices previously connected to the sensor using the IEEE 802.11 protocols to also have Bluetooth® protocols enabled. Enabling such Bluetooth® protocols uses more battery than having the IEEE 802.11 protocol adapter enabled. The sensor references a list of previously connected smart devices and attempts to connect with any in range, if none can be connected to, the sensor emits an audible alarm signal. Further, no application is required for the sensor to operate.

Abstract: Disclosed is a sensor and method for detecting one or more gasses in a sample. The sensor includes two sample tube sections, which allow for a larger sample, and correspondingly, more accurate measurement. Having two sample tube sections increases the total length of the sample path. However, placing the sample tube sections in parallel allows for the performance of the sensor to be enhanced, but the footprint of the sensor to remain unchanged. Light pipe material may be used to transport the light between sample tube sections. Further, light pipe material may be used to move the IR lamp away from the first filter tube section, reducing problems in the thermopile by dissipating heat from the IR lamp away from the sample tube section.
