ADS-B, or automatic dependent surveillance – broadcast, is used by commercial airplanes to broadcast their latitude and longitude along with other information to the air traffic controller. This information is transmitted at 1090MHz. ADS-B signals can be received using RTL-SDR dongle and decoded using software. In this project we use …

Presented here is a security system that lets you see a visitor while your main office door is locked. If you are in the middle of a meeting in a conference room and there is a visitor at the door, this system will send a notification to your smartphone with …

Here is a circuit meant for babies for generating various light patterns on eight LEDs. Lights pattern generator circuits available in the market are fitted with toys, and are used by babies for play and entertainment. These toys are bulky, analogue in nature and costly. The biggest drawback is that …

In this project, we will be using ESP8266 12e manufactured by Lolin to make a Chatbot that can control our home applications. To chat with our chatbot, we will use Facebook messenger platform. Also, we will integrate some AI into our chatbot using Chatfuel. It will then be integrated with …

Described here is a circuit of an automatic infrared (IR) faucet controller suitable for hand hygiene & water conservation at homes, hospitals and offices. This content was originally published here.

In this article, we discuss various sensor technologies that are used in specific areas of consumer electronic products. In electronics, whether you call it sixth or seventh sense, it is essentially the application of sensors with or without computer programs. Whether it is an invisible computer mouse, a blinkbot, a …

This temperature monitoring system is based on Cayenne Internet of Things (IoT) platform, NodeMCU microcontroller (MCU) and Message Queuing Telemetry Transport (MQTT) protocol. The authors’ prototype is shown in Fig. 1. Cayenne IoT Platform accelerates the development of IoT-based solutions, including quick design, prototyping and other commercialised projects. It is …

Electronic sensor systems extend their application to fields such as national defence, home, personal safety, office and industry. Are you familiar with the phrase “Big brother is watching you” from the novel Big Brother-1984 by George Orwell? In the context of modern technology, the concept of watching could be compared …

This article discusses what to expect from next-level field programmable gate arrays. Architectures of different field programmable gate arrays (FPGA) differ from vendor to vendor. Some vendors are Silego, Lattice Semiconductor, Xilinx, Microsemi and Achronix. Silego uses mixed-signal components. Whereas, Lattice Semiconductor is known for small form factors and ultra-low …

This project demonstrates a wireless security system in which four pyroelectric infrared (PIR) motion sensors are placed in four sides—front, back, left and right—of the area to be covered. It detects motion from any side and turns on the audio-visual alarm. It also displays the side where the motion (intruder) …
