LM35 Temperature Sensor Module pack of 2

LM35 Temperature Sensor Module pack of 2

The LM35 Temperature Sensor is a highly accurate and easy-to-use analog temperature sensing IC designed for measuring temperature in Celsius. Unlike thermistors that require complex calibration, the LM35 delivers a voltage output linearly proportional to temperature, making it extremely simple to interface with microcontrollers such as Arduino, ESP32, Raspberry Pi (with ADC), PIC, STM32, and other embedded systems.

This LM35 Temperature Sensor Module pack of 2 is widely used in educational STEM projects, robotics, weather stations, industrial monitoring systems, home automation, battery protection circuits, and environmental monitoring applications.

Working Principle

The LM35 works by converting ambient temperature into an analog voltage signal. The output changes at a rate of 10 millivolts per degree Celsius, meaning:

• 25°C = 250mV
• 50°C = 500mV
• 100°C = 1000mV

This linear response makes coding and circuit integration simple and accurate.
