The latest offering from Teensy, Teensy 4.0 is the fastest microcontroller available today which is powered by ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip. Teensy 4.0 has the same dimensions (35 x 18 mm) of Teensy 3.2 and maintains compatibility with most of the pin...

Over time we have built quite a number of data logger projects, but the emergence of more modern development boards, sensors and platforms mean there is an opportunity to add several new features to data-logging devices. For today's tutorial, we are going to build a datalogger based on...

Introduction The electric resistance is a property that characterizes how a particular component creates an opposition to the flow of current when a voltage difference is applied to its terminals. In this tutorial, we will focus on the opposition that a resistor generates when an AC...

Allegro Microsystems’ device consists of a linear Hall sensor circuit with a copper conduction path located near the surface of the die. The Allegro ACS711 provides economical and precise solutions for AC or DC current sensing in <100 V audio, communications systems, and white...

The mass flow meter SFM4300 features improved sensitivity and precision, even for low flow rates. The small, compact sensor is calibrated for air, O2 and N2O gases and – in contrast to its predecessor, the mass flow meter SFM4100 – it can also be used to monitor gas mixing. With a...

In one of our previous tutorials, we examined the development of a DIY-Geiger Counter showing the efforts of "Instructable" user Prabhat who combined the ESP8266 with a touch screen display to create a truly intuitive version of his Geiger Counter. He recently created an updated version...

Recent campaigns around environment pollution helped increase the awareness around it with more people beginning to monitor their pollution footprint while also paying attention to the quality of air they breathe in. Different countries and communities have now several Air quality...

Technology is continuing to transform the automotive industry, particularly the EV segment. The decrease in battery cost and increase in battery capacity, coupled with other advantages such as zero-emission, noiseless operation, and overall cost savings have led to EVs becoming...
