To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need any moving parts. [Andy] demonstrates building an ultrasonic anemometer using a cheap after-market parking distance sensor kit and an Arduino. Demo video after the break. Aside from […]
Norman is a climatic simulation library designed to run on an Arduino Uno for indoor and greenhouse automation projects. Arduino Library for mathematical climatic simulation of natural daylight, temperature, and humidity cycles using minimal data sets. Given a set of parameters for a target locale, the library returns values for temperature, dew point, Relative Humidity, and
Air Quality Prediction is a project that balances Arduino development and Machine Learning. I have always found the world of machine learning captivating but was never able to run models on real-time data. Arduinos provide the solution with a vast array of sensors supported on their microcontrollers. As a result, I knew that I wanted
There are many smart devices available to us that are able to detect our heart rate and other bio data by using a method called photoplethysmography (PPG), a concept of how blood is able to reflect red light while absorbing green light. The device can detect the amount of blood flowing, so when there’s more
This Arduino Nano Shield consists of a Light sensor, a Magnetic field sensor, and Temperature sensor. The shield can be used to develop various projects required light sensing, magnetic field sensing, and temperature sensing. All sensors provide analog voltage outputs, so each output is connected to analog inputs of Arduino Nano. SENSORS OPT101 High Sensitive

When you are responsible for maintaining devices at a client’s location, software tools like remote desktop and SSH are great, but sometimes they are not enough. For some problems, you need to get eyes and hands on the device to figure out what’s going on and fix the problem. This is a challenge [Will Donaldson]
We have built quite a number of weather stations in several past tutorials, with each one differing from the other by the use of a different sensor, different display, etc. Today, we are going to build another weather monitoring station using the BME280 Temp and humidity sensor from Adafruit and an OLED display. The BME280 is an integrated
TDK Corporation’s announces the immediate worldwide availability of the Chirp CH-101 MEMS-based ultrasonic Time-of-Flight (ToF) sensor. This ToF sensor utilizes a tiny ultrasonic transducer chip to send out a pulse of ultrasound and then listen for echoes returning from targets in the sensor’s field-of-view. By calculating the ToF, the sensor can determine the location of

City dwellers often spend a large amount of their time indoors, either in an office, at school, or simply at home. Urbanized spaces, however, tend to trap and develop bad air quality as they get more insulated for energy efficiency purposes. The concentration of CO 2 is an indicator for bad air quality. Today´s market solutions for
