Description

LM35 series Temperature Sensor is a precisely integrated circuit whose voltage output is linearly proportional to the centigrade temperature. These sensors have an added advantage over kelvin calibrated sensors and do not require the subtracting of constant voltage from its output to obtain convenient centigrade scaling. Our product need not to be calibrated or trimmed to normal accuracy of ±1/4 °C at room temperature and ±3/4°C over a full -55 to 150°C temperature range.The low output impedance, linear output, and precise inherent calibration of these temperature sensors makes the interfacing to readout or control circuitry easily.These sensors can be used with single, plus or minus power supplies because it draws only 60 mA from its supply and has very low self-heating, less than 0.1°C in still air.
