Raspberry Pi-based systems require internet connectivity to work at full potential, this is especially true for applications like IoT, image processing, remote sensing, and other cloud-based applications. Consider the case below: You need humidity sensor data in an agricultural field 200 meters away from your control unit, but there is no internet access or a power outlet in…
“Good morning. It’s 7 A.M. The weather in Malibu is 72 degrees…” these were the first words of JARVIS when being introduced in the Marvel Cinematics Universe. Most Iron Man fans should be able to recollect this scene and remember that JARVIS was able to open a window (kind-of) in the morning and give updates on time and weather. In the movie, the window Glasses were actually…
Ever wondered why do you need Node-RED with Home Assistant? It looks like that both Home Assistant and Node-RED do the same things but they excel in different areas. Home Assistant’s main power is its ability to interface and control any smart device existing at the moment. The main method of creating automation in Home Assistant is by using…
ESP32 series microcontrollers are low-cost, low-power system-on-chip microcontrollers that come with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series comes with Tensilica Xtensa LX6 microprocessor in both (dual-core and single-core) variations, and it has inbuilt antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management…
Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In this post, we will…
Edge Impulse Studio is a machine learning platform that enables developers to generate Machine Learning trained models in the cloud and deploy them on microcontrollers (e.g. Arduino and STM32), or single-board computers like the Raspberry Pi. Initially, Edge impulse didn’t support the Raspberry Pi but on April 2021 Edge Impulse announced their full support with Raspberry Pi…
Inverter circuits are often needed where it is not possible to get AC supply from the grid. An inverter circuit is used to convert DC power to AC power and it can be divided into two types that is Pure Sine Wave Inverters or Modified Square Wave Inverters. These pure sine wave inverters are very expensive, where the modified square wave inverters are inexpensive. Learn more…
3D printers have become an essential aspect of quick prototyping and have reached out to a wide range of makers and engineers. But most of these printers are hobby grade and hence require constant tinkering and repairs to keep them working. Among all challenges, 3D printer filament breaking or tangling is one of the most common problems that everyone who…
Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify our sound…
Detection of air flow is useful in many projects and applications. Here we are building a very simple circuit to detect the air flow presence. This circuit doesn’t require any fancy stuff like Resistance Temperature Detector (RTD) or Zener diode etc. Here we are using a simple AC bulb filament with some cheap component to detect the air. This is very interesting project…
Here we are going to build a motion-controlled fan project using ATmega328 and RCWL-0516 Doppler RADAR Motion Sensor. This project will eliminate the need of manually turning on/off the room fan while entering or leaving the room as it can automatically turn on the fan upon detecting the motion. For example, once motion is detected, it will turn on the fan…
The ESP32 based project is basically to detect the theft from the energy meter used in households as well as in the commercial sector. There is two based meter one for the distribution line and one for the consumer side. Whenever the distribution line load reading does not match the consumer side reading; that means there is some kind of power leakage in…
