#79575 - RE: sensing temp and voltage of a battery Responding to: ???'s previous message |
I chose the ADC 0804 and the LM35 for the temperature, and an analog multiplexer between them, but the sensor need negative voltaje to tell -20C. How can I solve this? I don't want to produce negative voltaje because I only have +12V.
Again the significance of reading about components before choosing them but I don't know how to connect the output to the ADC The the two diode schematic in the sensor datasheet has Vout+ and Vout-, the ADC has Vin+ and Vin- it should be no mystery "how to connect". Erik |
