I ordered these and will let you know. Datasheet here.Hyena wrote:Anyone had a play with thermistors yet ?justin_le wrote:Temperature:This input can be either a 10K NTC thermistor,
I don't know much about them but there seems to be a fair variation in price ranging from THESE that are under $2 for 10 or others that are $5 each or more.
The LM235 seems to have a similarly suitable temperature range up to 125 oC. The LM135 goes up to 150 oC which would be nice for those pushing it to the limit but they're heap more expensive.
I'm happy for the CA to step in around 120 though!
If possible, I will install 2 in the motor and two in the controller. I also have the Analogger, so will be able to compare data.
In the meantime, I hooked up a throttle and it is great to see the min and max voltage output on the CA. That alone is already a big improvement. I calibrated the CA/external shun combo without issues using fixed iCharger current through the shunt.
Justin, as I run 30S with an external shunt (0.35 mOhm), I run in high settings. Still I can not have LVC higher than 99.9V, which is way too low for my 30S lipo. Would prefer another digit here, so I can get at least 105V LVC.
Also, even with the temp log off on the Analogger, hooked onto the CA v3 beta, the Analogger shows me 3 to 5 additional collumns that I still need to identify. Having the CA send out a header when starting up, or sending out the summary stats with a header when shutting down would be a great help. Summary stats could include min, max, mean. Furthermore, having a time stamp in the CA would be very helpful, because without knowing this it is now less then accurate to link the CA data with GPS data. I know having a clock in the CA would be a bit too much, but if it could retrieve the date-time from the Analogger, and send it along in the CA dataset as timestamp, it would be great.
Tekletik, your guide is really great. However, I think it is worth it to add some info how to connect the CA to the controller regarding throttle output, as explained in your post here. I will assume that in the final version, the CA will come with a controller connection anyway, but for now it would be a good addition.
