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 ...

Local company builds new bug-like robots to teach programming to schools

We often write about the growing trend of tech companies to make robots for the purposes of teaching the youth how to code. Today we’re doing that again, but this time telling the story of a local tech start-up doing this rather than some big international company. Because South Africans should also be learning about robotics, so why not have a local company that can help us get up to speed with where the w ...

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 ...

Easy IoT Weather Station With Multiple Sensors

A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand. The station creates a web site that monitors temperature, dew point, humidity, pressure, light index, and rain (Thingspeak channel). It’s a p ...

Arduino’s new Nano board family is more powerful and affordable

Arduino's Nano line will soon welcome four new products. They're all small boards like the classic one, making Nano a family of small boards meant for compact projects. All the new boards boast low energy consumption and processors more powerful than what the classic has. Even better, they're all pretty affordable: the most basic entry called Nano Every, which you can use for "everyday" projects and can rep ...

Tyre pressure monitoring system using Bluetooth Low Energy

Author: Maurizio Di Paolo Emilio A tyre pressure monitoring system (TPMS) aims to monitor air pressure on various automotive systems. The most common TPMS sensors mainly use sub-GHz radio standards to transfer information to the vehicle’s computer. There are two different types: direct (dTPMS) and indirect (iTPMS). The use of bluetooth low energy (BLE) connectivity makes it possible offering a high performa ...

Arduino Parking Assistant

Those of us who have small garages know the frustration of parking a little bit too far in or a little too far out and not being able to walk around the vehicle. We recently bought a larger vehicle, and it has to be parked perfectly in the garage to walk around the front and back. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working ...
