infrared Motion-Sensing Relay Switch
This circuit is designed for use with all kinds of mediumpower automobile/domestic 12V DC loads. It is a simple solidstate relay (SSR) switch, controlled by a standard passive infrared (PIR) motion sensor module.
PIN Diode Based Fire Sensor
Here is an ultra-sensitive fire sensor that activates an alarm when it detects fire. Thermistor based fire alarms have a drawback; the alarm turns on only if the fire heats the thermistor in close vicinity.
Fridge temperature and humidity Indicator
We can measure temperature and humidity inside
the fridge using a normal temperature-humidity indicator but relative humidity (RH) could be inaccurate in that case.

5G: The Next-Generation Network
With time, generations change, whether it is mankind or technological. But the biggest and
fastest changes have only been noticed in the communication network generations in the last few years.
Test & Measurement
The Latest In Scopes
Although the performance of oscilloscopes has consistently improved over the years, their basic functionality remains the same. ďWhether the application is monitoring a patientís heart signal or debugging the timing glitches at the output of a fieldprogrammable gate array, in general, these display the voltage variation of the signals connected to their input channels with respect to time,Ē explains Shayan shani, editor at Analog Arts Inc.
Wearable Devices: Essential Inputs for Design Engineers
In the first part of this article we defined and classified wearables, and covered the designing and manufacturing phases of the life cycle of a wearable product.
Signal Processing With Sonic Visualiser
With electronic signals becoming a way of life, it is important for researchers to process and then analyse these effectively. The signal could simply be a spectrum from MATLAB or the graph of a song.
R: A Data-Analysis And Statistical-Computing Tool
R is a statistical-computing environment that consists of a language along with a run-time environment with graphics, a debugger, access to certain system functions and the ability to run programs stored in script files.
