Gas Sensors - Eric Schinkoeth Reis Barbosa da Cruz - Mar 10 7:31:00 2005

Hello,

	As a university homework, I must design a gas sensor system and, of 
course, I'll use a MSP430! The sensors can be of any type of gas, but after 
a few hour in Google, I can't find a place to buy them, only ready-to-use 
products.
	Took a look at distributors like Farnell also, with no return.
	Does anyone knows where can I buy these? They must be cheap and sold in 
quantities of 1~2, but don't need precision.

Thanks in advance,

Eric Cruz




Re: Gas Sensors - fqrley - Mar 10 8:12:00 2005

You could go for a calorimetric gas density sensor.  The idea is to
build a wheatstone bridge type of circuit with PT100 and PT1000 type
RTDs in the bottom legs.  Once the circuit gets enough current for the
PT100 to self heat, the balance of the circuit will become very
sensitive to air movement.  It will also be sensitive to changes in
thermal conductivity at no flow, which is more or less related to gas
density.

Humidity has become very common lately, try google.

Any type of gas, but can you measure any parameter of the gas 
(pressure, temperature, ...)?

Farnell do have some oxygen sensors, but not low cost.

Elfa (www.elfa.se/en) do have some relatively cheap ~10 Euro gas 
sensors. You could have a look at PN: 73-093-21, 73-093-39,
73-093-47, 
73-027-22.

Here is a place for a CO sensor.

Thanks a lot for everyone's help, now I have a lot of sources for sensors, 
and I'll put as much as I can pay or have enough time to implement!!!

Re: Gas Sensors - hc08jb8 - Apr 3 8:23:00 2005

Hello

Anyone know of any small exhaled Nitric Oxide (eNO) sensor suitable 
to use with an MSP?

I did google and found some that arent suitable for a portable design.

Thanks
Jay

Re: Gas Sensors - Eric Schinkoeth Reis Barbosa da Cruz - Apr 3 19:37:00 2005

Hello,

The only sensor I found that could be suitable for you is the TGS2201, from 
Figaro (http://www.figarosensor.com/gaslist.html).

I hope this one fits your needs,

Eric Cruz

Re: Gas Sensors - hc08jb8 - Apr 4 4:15:00 2005

Thanks Eric,

Apart from the operating voltage the sensor seems to suitable. 
Meanwhile I did also come across this:-
