Hi,
I'm new in electronics.
I have a problem with Voltage difference. I want to take voltage difference between two points, but respect to the ground.
Here is the schema: LM35 is temperature sensor and Vout is analog voltage proportional to the temperature :
I wаnt Vout to supply to one input chanel of analog do digital converter. I can supply + to one channel and - to another input channel of ADC and calculate the difference, but i wаnt to use only one channel and supply to this channel difference voltage Vout betwen + and - . What is the most accurate and easy way to generate this voltage respekt to the ground ?
