Abstract: A gas monitor apparatus includes a sorbent material that adsorbs a target gas based on a concentration of the target gas in a monitored environment and a reference material that does not respond to the target gas. The gas monitor also includes a first thermistor disposed within the sorbent material and a second thermistor disposed within the reference material, the first thermistor to provide a first indication of a first temperature of the sorbent material and the second thermistor to provide a second indication of a second temperature of the reference material. A processing device determines a concentration of the target gas based at least in part on a differential measurement between the first temperature and the second temperature.

Abstract: Gas sensors for the detection of rare events consume very little or no power. The sensors include materials that interact with a target gas. Accumulation of the target gas on the sensor materials leads to a change in electrical properties of the sensor. The sensors may have high gain, meaning that a large electrical change is induced upon gas accumulation. The sensor might change from an extremely high resistance (open circuit) to a measurably low resistance, or it might change from a relatively low capacitance to a high capacitance. The gas sensors are connected to electronics that can transmit an alarm signal after gas has been detected. The electronics may be in a low power sleep mode until awakened by a signal from the sensor.
