What Does VOX Mean on a Walkie-Talkie?

VOX is a voice-activated sound sensor which works by detecting the differences in air pressure. It converts audible voice and sound data into electric signals. In the case of a walkie-talkie, the transformed electric signals trigger or turn on the transmitter. In the absence of these electric signals, the transmitter goes back to its default off status. Modern Replacement. The early makes of ...

How Do Smoke Detectors Work? - The Spruce

2019-11-16· An ionization smoke detector is roughly similar to another type of safety alarm: a window sensor burglar alarm. A sensor on the window and a sensor on the window frame touch, completing an electrical circuit. When that circuit is broken, the alarm sounds. Smoke detectors work with the same circuit completion/break concept, though with a difference: There is no physical contact between the …

VOC Room Sensor Installation and Operation Instructions

Humans exhale Volatile Organic Compounds (VOCs) as well as CO 2. The BAPI sensor is able to measure these VOCs, therefore it is as good an indicator of space occupancy as a CO 2 sensor. The BAPI Sensor is different from other VOC sensors because it has been optimized for Demand Controlled Ventilation (DCV). Using a calibration algorithm, the sensor value is converted to an output with a high ...

Single resistive sensor for selective detection of ...

2020-10-15· Selective detection of harmful gasses and volatile organic compounds (VOCs) in the ambient has become a major challenge. Primarily, semiconducting metal-oxide based gas sensors sense various gases simultaneously, hence their selectivity is poor. This paper presents a single chemiresistive metal-oxide gas sensor for identification of multiple VOCs accurately by employing highly sensitive ...

Detection of hazardous volatile organic compounds (VOCs ...

2016-11-01· A most important feature to consider is the selectivity, the ability of the sensor to discriminate the VOC of interest when this is present together with similar others. The selectivity, sometime also defined as cross sensitivity, can be defined by an interfering ratio as: (5) K = S A / S B where S A and S B are the responses of a sensor to the target VOC and an interfering VOC ...
