LM35DZ Temperature Sensor Original

🌡️ LM35DZ Temperature Sensor – TO-92 Package (Original)

Precision Centigrade Temperature Measurement

The LM35DZ is a high-precision analog temperature sensor with an output voltage linearly proportional to the Celsius temperature. Unlike thermistors, it requires no external calibration, providing accurate readings from 0°C to +100°C. The TO-92 package makes it compact and breadboard-friendly.
