Thanks!
I will read the document and soak up the knowledge!
I am very afraid that using a thermistor will be laborious, not accurate and expensive if I want to improve the accuracy within 0.5 degrees...
I'm still evaluating everything as possible.
The combination of thermistor errors makes me...
Hi Klaus,
Normally I use the digikey website.
What you said is more complete?
The Ci you quoted me has great features, but the solder pad is too complex for my team to solder this package.
The ones I mentioned are simpler.
Hi Klaus,
Thanks for the answers, they help me to grow.
As for the energy cost for the thermistor, something around 10uA or less would be acceptable for my application.
I still don't understand the difference between using a mosfet and using a gpio to feed the resistive divider...
As...
Hi Klaus,
I didn't quite understand what I said (0.45 x FS). Can you explain better?
As for accuracy, what accuracy do you think we will achieve?
Energy consumption should be as low as possible, I don't have a target value.
My measurement will be once a minute.
VRef is not constant...
Hi klaus,
Thanks for your response!
My application requires super low power consumption.
Thanks for the tip on better choosing the resistor value of the resistive divider, I hadn't thought of that. That line idea was great.
Now I have a doubt in mind.
My SoC will run on 2 AA batteries, it runs...
Hello barry,
Thank you for your welcome!
I understood what you told me.
I would like a resolution of at least 0.1 degree celcius.
My SoC adc seems to have 12, 16, 18 and 20 bit options. Apparently it is more common to use the 16 bit. Perhaps we can use it as a reference.
As for the...
Hello guys.
I'm using an efr32bg22 Bluetooth module and would like to read a thermistor with it!
I've never used a thermistor.
Reading a little about the subject, it seems a little complicated to me.
There are some formulas for obtaining a conversion but apparently the best way is to use a...
