Abstract
A gas concentration determination system includes an acoustic sensor generating acoustic sensor data and a humidity sensor generating relative humidity data. A modified relative humidity is determined based at least in part on the acoustic sensor data and the relative humidity data. A gas concentration is determined using the modified relative humidity and the acoustic data. Using the modified relative humidity instead of the relative humidity data may reduce false positives in detecting gas leaks in HVAC systems, for example.
Claims20
A method of determining a gas concentration, the method comprising:
- receiving, from a humidity sensor, a measured relative humidity of a gas sample;
- receiving, from an acoustic sensor, acoustic sensor data associated with the gas sample;
- determining, based at least in part on the acoustic sensor data, a calculated relative humidity of the gas sample;
- and
- determining, based at least in part on the measure relative humidity and the calculated relative humidity, a concentration of a gas in the gas sample.
A gas detection sensor comprising:
- a humidity sensor generating relative humidity data associated with a gas sample;
- an acoustic sensor configured to generate speed of sound data associated with the gas sample;
- a processor;
- and
- memory storing instructions executable by the processor to perform operations comprising:
- receiving, from the humidity sensor, a measured relative humidity of the gas sample;
- receiving, from the acoustic sensor, the speed of sound data associated with the gas sample;
- determining, based at least in part on the speed of sound data, a calculated relative humidity of the gas sample;
- and
- determining, based at least in part on the measure relative humidity and the calculated relative humidity, a concentration of a gas in the gas sample.
