Water Level Measurement

Here we discuss on low cost continuous liquid level monitoring system based on MPX5010DP differential pressure sensor. Most of the traditional measuring systems were designed and implemented by complicated hardware circuitry. It made the product expensive, with low functionality and with limited precision. With virtual measurement technology, more of the instrument can be substituted by software. Using this approach the cheaper and more versatile measurement system can be developed. The method for obtaining liquid level with one differential pressure sensors MPX5010DP Continue reading Water Level Measurement Using Arduino →

Introduction

In many circuits we need to display battery voltage level, most of the battery operated device need indication for battery level such as solar lamp, charger circuits. LEDs are most popular to show status of system such as power on/off, Level indication Low, High, Medium etc. LEDs are available in various sizes and colors, they are simple to use and offer design flexibility. Let’s start with our first example LED as voltage level indications. This can be useful in battery level indication applications. Continue reading Single LED as Voltage Level Indicator →
