Simple 5V DC Power Supply

image-118
In any electronic products or projects there is always a source of power for the system to work. This is called a power supply. The source of this power can come from different sources like the mains AC voltage, a battery or even from a renewable power source like a solar panel wind turbine or fuel cell to name just a few. The most common source of power is usually the mains AC, with this power, we need a transformer to convert the 220V 50Hz mains or the 120V 60Hz if you are living in the United States of America to a lower voltage required by the electronic circuit, this can be typically between 6V and 12V when 5V regulated DC is needed. In this article we are going to design a simple 5V DC power supply that can be used to power your Microcontroler projects using the 7805 voltage regulator.

Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor – MikroC

image-136
Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using MikroC Pro for PIC compiler. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – mikroC

image-133
The MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. It can measure pressures between 15kPa and 115kPa. Note that 1 atmosphere of pressure at sea level is equal to 101,325 Pa or 101 kPa. This sensor is ideal for microcontroller based barometer, altimeter, data logger or weather station applications. In this article, we're gonna create a simple Digital Barometer using mikroC Pro for PIC compiler.
