#15592 - RE: Ref. voltage is 5V from 7805 |
Hello,
Thank you for your answers about temperature mesurement. I like mesure the external weather temperature. The range is approx. -30 to to +30 degree Celsius. The Dallas is probabely the best hardware solution but need more software work. I am ok with the Eric answer. It is a VERY bad idea to use Vcc as a reference voltage, but this the design of my PCB. |
