When I think of sensors, the word ‘Aqara’ usually springs to my mind, first due to the almost complete set of sensor devices that they manufacture – motion, contact, leak, vibration, light, smoke, and of course the ubiquitous temperature and humidity combos you see ...
A sensor monitors the air for VOCs and provides an easy-to-understand visual display letting you know if VOCs are present in the room. The odour & VOC reducing pre-filter absorbs odours and must be replace every 3 months. The HFD360BC offers quiet operation and 6 air cleaning levels, including a new pet setting. The AirGenius 6 filters and circulates the room air up to 5x per hour.

The Figaro TGS 2620 VOC Sensor was used to measure the VOC concentration within the sample. The VOC sensor is comprised of a metal-oxide semiconducting layer with an alumina substrate of a sensing chip. The VOC sensor was connected in parallel with a load resistor, as per the Figaro specifications [9]. The Arduino Nano microcontroller was
To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration. However, to avoid a cross interference no other VOCs should be present in the monitoring environment. For greater accuracy the sensor can be calibrated to the target VOC using a calibration gas of the target compound.
2020-10-07· This paper proposes a novel cholesteric liquid crystal (CLC) film–based dual-probe fiber sensor to monitor volatile organic compound (VOC) gas. The sensor consists of a 2×2 multimode fiber coupler, in which the two output fiber ends are covered by two types of CLC films (CLCF) with different pitches. It can be observed that the reflection peak wavelengths of CLCs shift to the red side as ...
Monitoring of volatile organic compounds (VOCs) is of increasing importance in many application fields such as environmental monitoring, indoor air quality, industrial safety, fire …

Aeroqual VOC Sensors Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs.
The C-21 VOC sensor can be used as a controller for external alarms, vent fans, or other device s. An integrated relay rated for up to 30 Volts at 130 mA will change states at the alarm level set by the customer. Dip switches in the rear of the device can be set to change the alarm state based on specific application needs. Also, dip switches will allow audible alarm to be turned ON or OFF ...
