LM35 Temperature Sensor (LM35DZ)

LM35 Temperature Sensor (LM35DZ) 

The LM35DZ is a precision analog temperature sensor IC that provides an output voltage linearly proportional to the temperature in degrees Celsius. It is factory calibrated in °C, so it does not require any external calibration or trimming.

The LM35 outputs 10 mV per °C, making it extremely easy to interface with microcontrollers, ADCs, and analog circuits. With its high accuracy, low power consumption, and simple 3-pin interface, it is widely used in temperature monitoring, control systems, and DIY electronics projects.

The LM35DZ variant is typically designed for 0°C to +100°C temperature measurement and comes in a TO-92 package.
