Parametric Amplifier

Parametric Amplifier

A parametric amplifier provides amplification via the variation of a reactance. This reactance is a parameter of a tuned circuit – thus the amplifier’s name. Consider a LC tank circuit that is oscillation at some microwave frequency. If the capacitor’s plates are pulled apart at the instant of time that the voltage across them is maximum  positive, work has been accomplished. Since the capacitance, C, has been decreased and the charge, q, must remain the same, the voltage across the capacitor, V, must have been increased since V = q/C.…

Monitor Changes in Network Switches using Python

automating arista switches configuration using netmiko

Monitor Changes in Network Switches using Python: Majority of the network failures are the results of either wrongly configured network devices or sudden changes in their network configuration, it shuts down the entire network or slows down the network performance. If someone breaks in and changes the configuration of the devices, network operators won’t notice until the network shows issues. And to solve these issues, if network administrators go on to manually track those changes in every single network device, it will take forever to check in a bigger network…

Automatic and Manual Temperature Control unit

author prototype of Arduino Based Automatic and Manual Temperature Control unit

Automatic and Manual Temperature Control unit: Automation have reached almost everywhere whether it is home automation or agriculture field. Automation system collect different parameter such as temperature, humidity etc. in real time basis and keep control of fan, moist control etc. But sometime we need manual control over various actuator or load like motor, fan etc. wither testing of load or when automatic system does not work. This project is the modified version of Arduino Based Temperature Controlled Fan. Manual mode is also considered as backup mode with which we…

Arduino PH Meter using PH Sensor

author prototype of arduino ph meter

PH is a scale with which we can determine whether the water-based solution is acidic or basic. PH is represented as the power of hydrogen or the potential of hydrogen (Source: Wikipedia). With the help of electrodes, we can measure PH of solution electronically which could be more beneficial to measure and automate PH of the aquarium, or hydroponic or aquaponic. So, in this article, we will learn How to make Arduino PH Meter. After completing this video one can Know about electrode and their working method Calibrate the module…

Interfacing DS18B20 Temperature Sensor with Arduino

author prototype of ds18b20

Interfacing DS18B20 Temperature Sensor with Arduino: This article is all about DS18B20 and its interfacing with arduino. DS18B20 comes in two variants: Normal and waterproof version. Normal version is available TO-92 and uSOP. Let’s start with introduction. Description of DS18B20 It is digital programmable temperature sensor based on one wire communication i.e. it requires only data line and common GND. Power supply is optional because this sensor can drain require power supply from data line and this mode called parasite mode. DS18B20 can provide different temperature resolution is 0.50C, 0.250C,…

 LM35: How to get Stable Temperature Reading

author prototype of how to get stable output

One of the most common analog temperature sensors used for temperature monitoring and controlling is LM35. According to the manufacturer, LM35 is a precise centigrade temperature sensor, but the reality is a bit different when we directly wire this sensor with Arduino. There are various reasons for fluctuation in output. Here in the article ” LM35: How to get Stable Temperature Reading” we will address almost all the reasons and solving one by one. But before that let’s see how this sensor work. Basic Working of LM35 According to the…
