Short update on the timeline for the VOC sensor
Delivery:
- i expect to have the first sample PCBs by end of March
- The first week of April i will do some mass testing to see how individual sensors behave
- if everything is alright i expect to start shipping from mid of April
Results:
- So far it is clear that compared with a CO2 sensor, the VOC sensor output does not get beyond 1800 ppm from human activity
- on the other hand, spraying some deodorant increases the reading much more, since the sensor reacts on ethanol and simillar gases
- i am yet to test it against some cigarette smoke. The problem is that here it is forbidden to smoke inside public areas, and since i am not smoker it is a bit hard to find a closed space to test it
Extending existing devices:
- To extend existing devices it is enough to connect the VOC sensor with 4 wires + some splitter - i will include them
- most probbably it wouldn't fit into the existing boxes, so i will also create some small enclosure, that can be glued to the main box
