The rise of Internet of Things (IoT) has taken the evolution of sensors to a completely different level. Sensors are an integral part of any engineering company that works on the IoT platform. Various industries and organizations use different types of IoT sensors like temperature sensors, proximity sensors, water quality sensors, etc. as per their requirement. Founded…
Flow rate measurement involves the determination of the quantity of fluid passing through a specified surface area of a vessel at a particular time. Like all form of measurements, it has everyday life applications ranging from its use in monitoring water and gas consumption for bill estimation to more critical industrial applications (e.g large scale mixing of multiple…
For one of our projects, we tried to Interface LM35 Temperature Sensor with Arduino but were unable to do so. Yes, what seemed like an easy task became a whole day's effort. We initially assumed the sensor was defective, but after testing about 15 sensors, we saw the same issue over and over again; all of these sensors came from the same lot of 85 sensors we had in…
Road accidents are counted as one of the leading causes of unnatural deaths and the majority of the road accidents that take place are caused by human error. We all know that transportation automation reduces human errors. Vehicle automation is not enough instead, it is equally critical to establish safety assurance in the autonomous vehicle before being deployed on the…
In my previous article on EMI, we examined how the intentional/unintentional nature of EMI sources and how they affect the performance of other Electrical/Electronic devices (victims) around them. The article was followed by another one on Electro Magnetic Compatibility (EMC) which provided insights into the dangers of EMI and offered some context to how poor EMI…
Harmonic distortion has always been a problem for electrical engineers as it leads to heavy power loss in AC induction motors and transformers. These losses in AC induction motors leads to excessive heating, which happens because of additional copper losses and iron losses (eddy current and hysteresis losses) in the stator winding, rotor circuit, and rotor laminations. This…
Anyone who deals with electronics will have come across waveform generator circuits like rectangular waveform generator, square wave generator, pulse wave generator, etc. Similarly, Bootstrap Sweep Circuit is a sawtooth waveform generator. Generally, the Bootstrap Sweep circuit is also called as Bootstrap Time Based generator or Bootstrap Sweep Generator.

Soil health monitoring, irrigation scheduling, hi-tech greenhouses, evapotranspiration studies, watershed management, land reclamation, drought, flood forecasting, etc. play a vital role in farming. Farmers in India have been facing a lot of problems in terms of real-time and on-field data analytics. Undoubtedly, there are certain companies that offer the solution but the…
For the last many years, automobile manufacturers have turned their attention towards self-driven cars. It all became serious when Google launched its self-driving car project (Wamyo) in 2009. A few years later, Elon Musk announced Tesla would build a self-driving system into its cars and in November 2018, Tesla launched a feature called Navigate on Autopilot. By 2013, major…
Direct Online Starter or DOL is a simple electromechanical system designed for switching and protection of Induction motors.
We all know that motors consume electric power horribly and this high power consumption is the result of current drawn by the winding of the motor. So higher the current drawn by the motor, the higher will be the power…
A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal, which has a different frequency, depending on the broadcasting station. The IF signal is then amplified by a strip of IF amplifiers and then fed into a detector that outputs the audio…
Transport is one of the major contributors to global warming, representing more than 23% of global energy-related carbon dioxide emissions. Today, Electric Vehicles are looked upon as an alternative green way of commutation but to make EVs more affordable and practical, we need much more efficient batteries and battery-charging technology.
