GardenBot - open source garden automation project The Power Module This page outlines two different kinds of power supply. One is for DC power (this is to control low-voltage things like the water valve). The other is for AC power (this is to control standard, houshold voltage and is more dangerous to work with). Local circuit For this how-to, we're going to start with the local circuit.
Temperature & Relative Humidity Datalogger using DHT22 and Arduino Uno - Open Source Building Science Sensors The following tutorial will guide you through the process of building your own data logger for reading temperature and humidity and storing it to the SD card at any given interval. We will use one of the most common Arduino boards for this project: the Arduino Uno. This tutorial is aimed for beginners who are new to the Arduino platform. Note: If you’re not familiar with how a breadboard works, check out a simple tutorial by SparkFun.
Micro SD Card Breakout Board Tutorial Now that your card is ready to use, we can wire up the microSD breakout board! The breakout board we designed takes care of a lot for you. There's an onboard ultra-low dropout regulator that will convert voltages from 3.3V-6v down to ~3.3V (IC2). There's also a level shifter that will convert the interface logic from 3.3V-5V to 3.3V. That means you can use this board to interact with a 3.3V or 5V microcontrollers. In this tutorial we will be using an Arduino to demonstrate the wiring and interfacing. ESP8266 Serial WIFI Module - ITEAD Wiki Overview ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.
ESP8266 WiFI temperature and humidity sensor In this tutorial we will show how to make Wifi temperature and humidity sensor with Arduino, ESP8266 WiFi module and DHT22. Data will be sent to EasyIoT server. Materials: See buying guide at the end of tutorial. -ESP8266 module A Simple IoT Project with the ESP8266 WiFi module – electronut.in December 19, 2014 | Arduino , Circuits | A Simple IoT Project with the ESP8266 WiFi module This is one of my older ESP8266 articles. Please check out my more recent ESP8266 projects below: The ESP8266 WiFi Module The ESP8266 is a WiFi module that costs less than 5 USD.
ESP8266 first connection i’ve bought an ESP8266 module on ebay for less than 4€ few month ago, a good description of the chip is avalaible here : and a procedure to update the firmware the SDK is now available on linux see the page explain each AT command in detail the chip only accept 3.3V so i use a PC power supply (i still waiting for an MB102 power supply module) and a 3.3V serial / USB converter pl2303 from prolific and the photo below describe my connection for the fist connection i use minicom , launched using the option -D to set device (user shall be member of dialout group) at 115200baud 8N1 works for me
ESP8266 Quick Start Guide This page is meant to be a quick introduction to the ESP8266 for those who are confused by all of the information available on the various blogs and forums who just want to try out this exciting board in the shortest possible time. This guide is for Windows users who want to use the NodeMCU environment. Not counting waiting for hardware to ship to you (1-10 days), you should be able to use your ESP8266 for something useful in less than an hour. Ready? What do I need to buy? You will need an ESP8266 development board. Arduino Projects Order from eBay THIS ITEM APPEARS TO BE DISCONTINUED BY THIS VENDOR or good info here: and here: (translated to English)
