LM35 Temperature Sensor 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:http://www.electronicwings.com/sensors-modules/lm35-temperature-sensor You… Continue reading

Measuring a Temperature with DS18B20
DS18B20 is a digital temperature sensor which measures temperatures from -55°C to +125°C. It uses 1-Wire communication protocol. We have only one data pin for sending and receiving data. For more information see DS18B20 datasheet. In this post I will use Raspberry PI-III as a micro controller. For data pin I chose GPIO26. Before using this pin… Continue reading
