BMP280 is a high-precision sensor module chip that can measure atmospheric pressure and temperature in the air. Not only that, but it can also measure the humidity in the air. This 6-Pin module supports both SPI and I2C interfaces. This chip uses a BMP280 barometric pressure sensor which, unlike other sensors, is pre-calibrated. Therefore, the
Resistor color codes are an essential aspect of working with electronic circuits. These color codes provide crucial information about the resistor’s value, tolerance, and temperature coefficient. With a variety of resistor types available, understanding the color code system is vital for professionals and hobbyists alike. This comprehensive guide aims to help you decode resistor color
As electronic devices become increasingly sophisticated and integrated into our daily lives, understanding the fundamental building blocks of these devices is essential. One of the key components in any electronic device is the printed circuit board (PCB), which houses and connects various electronic components. In this article, we will explore the most common circuit board
What Does PMOS Mean? PMOS (P-channel Metal-Oxide-Semiconductor) transistor is a type of field-effect transistor (FET) that is commonly used in electronic circuits. PMOS Symbol The PMOS symbol is a circle with an arrow pointing inward. The circle represents the p-type substrate and the arrow inside shows the direction of the majority carriers, which are holes.
PC817 Introduction PC817 photocoupler is an electronic component used for isolation amplification and signal transmission in various applications. It is a type of optocoupler that consists of an infrared light-emitting diode (LED) and a phototransistor or photodiode, enclosed in a single compact package. The LED emits light, which is then detected by the phototransistor or
What is NMOS transistor? An NMOS transistor is a type of field-effect transistor (FET) that operates using negative polarity. NMOS Structure It is made up of three regions: the source, the drain, and the gate. The source is where the current enters, the drain is where it exits, and the gate controls the flow of
