Advice on external temperature sensor

[Taggsladder 2]

Hello friends

 

Hope you are all doing great!

 

I need advice on an external temperature sensor for a MSP430G2553 project. I just need to read the "outside" temperature like a span of -30 to +80 celcius. I "just" ([emoji16]) want to know what the best/easiest/most common sensor would be. Of course I am a quite a newbie to this.

 

I have looked at some sensor like the lm35 but I read somewhere that it couldn't run at mcu voltage. Also looked at DS18B20 but its just a jungle for me and I don't know what to look for.

 

Requirements (not any particular order):

Low price

Can run at mcu voltage

Under 1 celcius accuracy

Nice to have some Energia examples to look at

The fewer pins the better, but not that important. I have loads of free pins.

 

Conclusion: A newbie friendly sensor to start out with

 

Sorry if the English is a little off, I have troubles sometimes finding the right words.

 

Best regards,

Andreas

I know Zeke has used these

I'm going to try one on my thermostat project, I'm also ordering a TI analog temperature sensor. But the digital output sensor I linked first is supposed to be a real good way to go.

I like this one: http://www.ti.com/product/tmp100

 

+/- 1 degree Celsius , 12 bit resolution . I2C.

 

Pretty easy to use, lots of I2C examples in the forum.

 

I even got some free samples of it from TI!

Thanks guys! I ordered lm61, ds18b20 and the tmp100. Will play with them and see what suits my needs best.

 

Have a nice day!

 

Best regards,
