designing a weather station

Hi guys,
PLease help me out here.
I have a school project which requires me to design a weather station, which measures;

wind speed, wind direction, temperature, and atmospheric pressure

[b]the system I design, should include signal conditioning and aplification for each sensor.

furthermore, the maximum input to the A/D convertor should be limited to 5V DC.[/b]

I have been trying hard to undertake this by myself, but I am finding it very hard. :frowning: … as I cant find any weather sensors that operate all under 5V DC. Furthermore Iam not sure whether I need to include an Op-amp or not… or how do I fo about the signal conditioning?

Please please please can somebody help me out.

Any help would be appreciated.

Many thanks

Here try this link

It is a SCP1000 pressure sensor with operating voltage of 3.3

thanks for your help :slight_smile:

iam thinking of using the MCP3002 Analogue to digital convertor, it has 2.7V to 5.5V supply

do you think it will work?.. therwise I might use the AD7822 3V/5V, 8-Bit, 2 MSPS Analog-to-Digital Converter

furthermore, does anyone know whether I will need a microprocessor for the weather station or not?

how about a 1-wire setup from hobby boards?

They have breakout boards for Humidity/Temp and Baro. I believe you would need some sort of processor.

ye, ur right!
I think the 1 wire solution is probably the best.
I have just spent alot of time checking through their products.

Just to confirm, i believe I need the following components for my weather station:
1) DS2450 1-Wire Quad A/D Converter (to convert the windspeed, wind direction into digital readings) ← Max input= 5V DC.
2) TAI8570 Barometric Pressure Module
3) TAI8520 Temperature Module
4) DS9097U-009 Universal 1-Wire COM Port Adapter (to get the readings on the computer).
5) TAI8515 Weather instrumentation kit (this measures the wind direction, wind speed, temperature)
Do i need separate modules for the Wind direction and Wind Speed, like I have used for the Barometric pressure and Temperature?.

Please tell me if I am going about it the right way, or if I have missed anything guys.

I really appreciate any help.

Many Thanks.

I don’t know what the class or level is, but if I was your teacher I doubt that I would consider that solution to be “designing a weather station”.

that is true!!
I guess I was trying to take a short cut! #-o

looks like i better carry on researching for components…

if anyone can point me to the right direction it would be very kind of you, :slight_smile:
