LM35 Temperature Sensor

Description The LM35 series are precision integrated-circuit temperature sensors, with an output voltagelinearly proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors calibrated in ° Kelvin, as the  user is not required to subtract a large constant voltage from  the output to obtain convenient...
