Interfacing LM35 with Atmega328P

LM35 is a precision  integrated-circuit temperature sensor. It’s output voltage linearly proportional to centigrade temperature. For example, 250 mV means 25°C. It does not require any external calibration circuitry. TheLM35 device is rated to operate over a -55°C to 150°C temperature range. In this post we will interface LM35 with Atmega328P 8-bit micro-controller.   Reference: […]
