Lm35

LM35 Precision Analog Temperature Sensor

The LM35 is a high‑accuracy, low‑drift analog temperature sensor integrating a precision platinum resistance thermistor and linear output circuitry. Its voltage output rises linearly at 10 mV per degree Celsius, providing a direct and straightforward interface to microcontrollers, ADCs or analog processing circuits without the need for calibration or complex algorithms.

Designed for low‑noise performance and wide environmental stability, the LM35 delivers ±0.5 °C accuracy over a broad temperature range, making it ideal for industrial process control, automotive climate monitoring, HVAC systems, and consumer electronics.

• Supply Voltage: 4–30 V (useful for battery‑powered and industrial power supplies)
• Output Characteristics: 10 mV/°C linear, 0 mV at 0 °C, 50–125 °C range
• Accuracy: ±0.5 °C (±1.0 °C worst‑case @ 5 °C to 60 °C)
• Common Use Case: Direct analog integration in Arduino/ESP32 projects for real‑time temperature monitoring and ambient data logging.
