The LM35 Temperature Sensor Module is a precision analog sensor designed to measure temperature with excellent accuracy and linear output. Unlike digital sensors, the LM35 provides a direct analog voltage proportional to temperature, making it highly reliable for real-time monitoring and data logging. It is widely used in Arduino, PIC, STM32, and Raspberry Pi projects for applications such as weather monitoring, HVAC systems, industrial controls, IoT devices, and academic experiments. For students and professionals in Bangladesh, the LM35 offers a cost-effective and dependable solution for projects that require stable, accurate, and low-power temperature measurement.
