Temperature sensor using PIC16F877A microcontroller

Temperature sensor using PIC16F877A microcontroller

In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16×2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any external calibration. The output voltage is proportional to Celsius temperature scale and changes by 10mV

AC Voltage measurement using PIC16F877A microcontroller

AC Voltage measurement using PIC16F877A microcontroller

Note: Microcontroller  PIC16F73  can be used instead of pic16f877a. This time we will see how to measure AC voltage parameters with the help of micro-controller. First we will know about AC voltage parameters, then we will do the whole work step by step. What is AC(Alternating Current): “In alternating current (AC, also ac), the flow of electric charge periodically reverses direction.
