View Full Version : Detecting carbon monoxide in a smoking lounge and a casino

Hello, I want to implement a system for detecting carbon monoxide in a smoking lounge and a casino, if it exceeds the parameters must be activated to extract air. Also:
1 .- I need to clearly define a sensor to be used.

2 .- Type of data delivery to the sensor reading.

3 .- How can I carry the signal from the sensor to the monitoring station and through that medium and that protocol.

4 .- How can I exploit the fact that delivery to the alarm line to extraction equipment.

5 .- cable type and length of cable so you do not have loss of signal (aproximadament 120 m. The sensor further from the monitoring station) is also needed if consulto amplifier.

5 .- How many signals you can receive the monitoring station. (with respect to the sensors that can connect to it)

6 .- The monitoring station can be connected to Internet or intranet? that protocol?

7 .- Power station monitoring

8 .- Each square, or how many cubic meters should be installed sensors (to cover area: 2660 m ^ 2 and 5.3 m height = 14048m ^ 3)

Thanks in advance and expecting a prompt response, I cordially dismissal.

I'm just making a wild guess here, but I suspect that the level of airborne soot and ash, smell of cheap perfume, and body heat/fumes in such a lounge would get far above the comfort threshold before carbon monoxide would become a major concern of any kind. You might want to use sensors like what are used on smoke detectors, so when the room gets too smoky, your air handler kicks on. Another option is a canary in a tiny cage: when it falls over dead, it hits a switch.

Hello Claudio,

from your questions I conclude that you have almost no experience in that field.

As carbon MONOxide is a high danger to life I recommend to make a contract with a professional company
that has experience in things like that to build a professional solution.

If you want a cheap solution: make the air-extraction running all the time and a simple watchdog that gives an alert if the system fails
combined with an air-heatexchanger to save heating-energy through the wintertime.

or simply use one of this carbon-monoxide warning systems like smoke detectors that start a loud beeping if
they detect carbon monoxide

if somebody dies inside your rooms
even the money to just get out of jail until judging will be more than a professional solution will cost

best regards

An indoor smoking ban would be much easier, as we have in most countries in Europe.

Leon, your laconic wit has me gasping.
