LM35D Analog Temperature Sensor Module (Precision Linear Analog Temperature Sensor)

The LM35D Analog Temperature Sensor Module is a precision temperature sensing module based on the LM35D integrated circuit, designed to provide a linear analog voltage output directly proportional to the measured temperature. Unlike thermistors, the LM35D does not require external calibration and delivers accurate temperature measurements with low self-heating characteristics. The module interfaces easily with the Analog-to-Digital Converter (ADC) inputs of microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi Pico, making it suitable for environmental monitoring, industrial control, laboratory experiments, and embedded system applications.
