The LM35 Temperature Sensor is a high-voltage analog temperature sensor that measures the heat or cold generated by an object and produces a proportional resistance, current, or voltage output. It has a sensor gain of 10 mV/°C and an operating temperature range of -55°C to +150°C. The LM35 has the following parameters: \n
