HIGH PRECISION ANALOG IO WITH DIGITAL PINS

Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need to get more esoteric. For years we ...

DIY Internet connected smart humidifier

I worked on creating a Internet connected worked on creating a Internet connected last week using my open source WiFi relay project as platform. We observe quite dry air at our house, I suspect this is due to the fact that we use fan coils for heating/cooling. Humidity levels at home are usually below the 30% mark, which poses a health risk along with uncomfortably dry air. I’ve found these interesting char ...

Air Quality Sensors on tindie.com

What is it? This is a small (17.9 mm x 10.3 mm) breakout board with Bosch's BME280 pressure, temperature, and humidity sensor as well as AMS' CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates of equivalent CO2 concentration in parts per million (400 - 8192 ppm) and vo ...

Evaluate the Swiss precision for free!

Top-class calibrated humidity and temperature sensors Sensirion already gained many fans. Mainly thanks to a fact, that they´re not only “sensors” but a ready-made solution with a pre-amplifier, ADC and other circuits, which directly provide a final value in a digital form. That´s why it´s not necessary to solve input portion (noise, shielding, power supply, length of wires,…). Moreover, their long-term sta ...

Water Out Of Thin Air

Due to the advances of technology, we are able now to produce water out of thin air without using the resources usually applied like mains utilities. Such approach would be perfect in places that lack natural resources like deserts. Working from the effects of direct solar radiation, a group of researchers at UC Berkeley had designed such a device with minimum mechanical parts and simple embedded systems. U ...

COULOMB TRANSISTOR — A NEW CONCEPT WHERE METAL NANOPARTICLES ARE USED IN PLACE OF SEMICONDUCTOR

A research group at the University of Hamburg has created a unique coulomb transistor that operates on the principle of the voltage control of the electron band gap in metallic quantum-dot nanoparticles. This Single-electron transistor represents an approach to develop less power-consuming microelectronic devices. It will be possible if industry-compatible fabrication and room temperature operation are achi ...

MCPCB – FIVE QUESTIONS YOU MUST KNOW

Introduction In recent years LED technology has experienced rapid growth in its adoption and general application. Like any other electronic device, LEDs make use of electricity. However, they generate a rather massive amount of heat that would usually be harmful to the lifetime and integrity of the circuit board within it. Metal Core Printed Circuit Board (MCPCB) Technology is responsible for the ability of ...

MAKING A DIGITAL CLOCK A LITTLE MORE INTUITIVE

Digital clocks are extremely useful and generally considered pretty easy to read. However, they can sometimes have rather arcane interfaces for setting the time and alarms. For [Michael Wessel], he noted that in the 1980s he had to routinely help his grandparents set their clocks for this very reason. That inspired his most recent project – a digital clock that’s intuitive to use. Many digital clocks work i ...
