The LM35 Precision Temperature Sensor is a low-cost analog sensor designed for temperature measurement from −40°C to +100°C. It operates like a two-terminal Zener diode and produces an output voltage directly proportional to absolute temperature at 10mV/K. The sensor requires a suitable bias resistor and can be connected to an ADC, voltmeter, or analog control circuit. An adjustment terminal is also provided for optional single-point calibration to improve accuracy.
Key Features
- Provides a linear analog output of 10mV per Kelvin.
