Some time ago, I tried to make an “Instructables Hit Counter” using the Instructables API, and an Arduino Uno with a wired network shield. However, with the limited RAM of the Arduino Uno, I was unable to get the system to work. A while ago, I noticed a similar project done by diytronics using a NodeMCU. This was just …

A simple temperature sensor using one LM35 Precision Temperature Sensor , Humidity Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature and humidity so you can use on your computer. I have taken data from my compost. The project is related to an existing …
My wireless temperature probes work by using an Xbee module to transmit readings from a TMP36 down to the Arduino base station. The XBees aren’t too cheap, coming in around £19 or $23 so I tried to be cheap and ordered mine from Sparkfun, I bought this XBee (series 1) with Chip Antenna and these breakout boards. I …

In this Arduino based project, we are going to control DC fan speed according to the room temperature and show these parameter changes on a 16×2 LCD display. It is accomplished by the data communications between Arduino, LCD, DHT11 sensor Module and DC fan that is controlled by using PWM. PWM is a technique by …

This is my first Arduino project aimed at helping me with my other hobby which is growing oyster and shiitake mushrooms indoors. In a nutshell, the controller takes in two temperature readings, 1 Humidity reading and 1 Co2 reading and triggers a set of four relays connected to mains power. Intended to be connected to …
n this tutorial we are going to show you how to setup your own temperature and humidity sensor. We are going to use a DHT22 unit, which is a low-cost digital output relative humidity and temperature sensor. The device includes a capacative humidity sensor and a thermistor to measure air temperature DHT22 Specifications Temperature Range: -40 …
Background I was in need of an affordable data logger for a project. I have access to MATLAB on all of my machines so it was an easy choice to build an Arduino based data logger that would easily interface with MATLAB R2014a. MATLAB is limited in both its sampling frequency (25 Hz) and its …
Introduction This is an Arduino controlled light sensing switching unit. Its main use is to control solar lights to turn on when it is dark outside, but it can work in many more applications. This guide will walk you through every aspect of the building process. Prior knowledge of the Arduino unit is not necessary …
Ever wanted to know how much solar power you could yield by putting PV cells in a specific place on or around your house? This Instructable shows you how to build a data logger based on an Arduino (or Genuino) Uno with data-logger-shield and a PV cell recording the electric power yielded during a sunny …
A fountain can make a nice decorative fixture for your garden. But it isn’t always easy to run a power cord out to where you want it. So I decided to run it on solar power. The system is controlled by an Arduino. This allows you to save energy by programming when the fountain will …
