How does Atmotube VOC sensor work?

Atmotube VOC gas sensor is responsive to a broad range of volatile organic compounds (VOC) and other gases relevant for indoor air quality, the present gas sensing technology is well suited for monitoring TVOC concentrations and for translating those into IAQ levels. Each Atmotube VOC sensor is production calibrated. Measurement range and accuracy. TVOC output range: 0 - 60 ppm: Typical ...

Adafruit SGP30 TVOC/eCO2 Gas Sensor

17/01/2018· The sensor adjusts to the best value it has been exposed to. So keeping it indoors the sensor thinks this is the best value and sets it to ~0ppb tVOC and 400ppm CO2eq. As soon as you expose the sensor to outside air it can adjust to the global H2 Background Signal. For normal Operation exposing the sensor to outside air for 10min cumulative time should be sufficient.

An Easy Way to Remember PNP and NPN Sensor Wiring ...

14/02/2018· Depending on the sensor’s internal wiring, there might be some current flow from the NPN input to the sensor, for example there may be reverse current that “leaks” through a protection diode or an LED in the sensor. This current flow might be high enough to falsely trigger the NPN input. When the PNP sensor turns on, it will connect +24VDC to the NPN input. This should not trigger the ...
