I have a lm335 that i need to test at 35degees. i have the sensor in the fridge that is set for 35 degrees.These are analog sensors, which according to the data sheet output a voltage proportional to temperature. The calibration seems to be 10mV/degreeC. i need to know the voltage that the sensor is putting out. i have it hooked up to a thermo controller and the sensor is getting the proper voltage for operation.i have a multimeter. can some one tell me how to read the value of the sensor.
