How to Control Your ESP8266 From Anywhere in the World

ESP8266

by Rui Santos @ randomnerdtutorials.com:

The most common questions I get about the ESP8266 WiFi Modules are: “Is it possible to control my ESP8266 from anywhere in the world?” and “How can I control my ESP8266 from anywhere?”.

I’m happy to announce today that I have a solution for that problem.

With the new version of Home Automation Server you can add an ESP8266 to your dashboard and control your ESP8266 GPIOs from anywhere in less than 5 minutes!

WiFi smoke detector

FU0VELAICX7JEWX-600x450

by Proto G @ instructables.com:

This is a simple WiFI Smoke Detector that texts me when it senses smoke. I made this for my battery storage area in case of a lithium polymer fire. I still have all of my regular smoke detectors installed and I don’t suggest relying only on this, but rather as an extra layer of protection. If I had a house I would install a proper fire alarm system that calls the fire department, but I live in a small apartment so I can’t. I can set this one to email and call the local fire department as well(local laws apply). In my county it is allowed as long as you register it with the fire department. Either way, I would rather call the fire department myself when I receive multiple texts.

ESP8266 MQTT battery monitor project

batterymon-600x550

Steve’s latest project, a wireless MQTT battery monitor:

This board uses an ESP8266 (ESP12), a Texas Instruments INA226 I2C voltage and current monitor, and a Texas Instruments LMR12010X buck converter. This board is designed to wirelessly monitor 12 volt batteries and power supplies using an external current shunt resistor. The voltage across the shunt resistor is measured differentially. The shunt resistor value and current rating is programmable in the firmware.

Even a small figurine can play a big performance

New aerial from 2J will surely not surprise you by its size, however features of the antenna are worth noticing.

2JW035 antenna measures only 52,5mm and is intended for WiFi and Bluetooth devices in 2.4 a 5GHz bands. The gain is 5dBi and the VSWR value is below 2.6:1. A big advantage of this antenna is a possibility of its versatile placing, as it contains a hinge.
So as to suit various customers´ requirements, the producer offers a possibility to order this antenna with three various connectors:

  • 2JW035-C20Nb is equipped with hexagonal black SMA connector
  • 2JW035-C675 is equipped with a round SMA connector
  • 2JW035-C442, which is also our standard stock type is equipped with a round black reverse-polarity SMA connector (RP).

For special applications, there´s also a possibility to order this antenna in a custom specified colour.

Detailed information can be found in the 2JW035 datasheet.

ESP8266 WiFi Shield for Arduino and other micros

FJMAB9BIBGCQ2Z8.MEDIUM

by drmpf @ instructables.com:

This ESP8266-01 WiFi Shield is an alternative to the Very Cheap/Simple Wifi Shield for Arduino and other micros. The Very Cheap/Simple Wifi Shield for Arduino and other micros uses an Adafruit HUZZAH ESP8266 module and is the simplest to wire up. However if you already have an ESP8266 module, you can use these instructions to make a WiFi Shield using it.

This instructable uses the ESP8266-01 module, if you have one of the other ESP8266 bare modules, provided the module has GPIO0 and GPIO2 available, then you can use these instructions. If the module makes GPIO15 accessible YOU MUST connect it to GND via a resistor with a value between 3K3 and 10K.

Wino… like Arduino, only smaller

20150624024339_Winoby Martin Cooke:

The Wino board is an Arduino-like stackable development system which is both smaller and cheaper than Arduino units and features built-in WiFi as standard.

The main Wino controller board measures 26.5 x 18.5 mm and fitted with an Atmel ATSAMD21 running at 48 MHz with 128 kB Flash storage and 16 kB RAM. The board uses the ESP8266EX WiFi module which supports all the 802.11 b/g/n standards offering P2P and soft-AP modes and TCP-IP / UDP, static IP and DHCP networking. The 27-pin stackable connections around the board periphery provide connections for 15 digital GPIO pins, 6 x 12-bit ADCs and a 1 x 10-bit DAC.

WIFI plant monitoring system based on Arduino MEGA and ESP8266

by techrm @ instructables.com:

Today we are going to show you our first experiment on the Internet of Things. For this purpose, we decided to use an Arduino MEGA instead of an Arduino UNO. That’s because Arduino MEGA has more than one serial port and this fact allows us to use the ESP8266 and the serial monitor at the same time. As written in the title, we’ll see how to monitor some of the most important plant growth factors*. These parameters are: Ambient temperature and humidity Soil moisture and temperature Illuminance

Pozyx shield gives position

by elektormagazine.com:

Resolving the position of free roaming robots can be quite challenging. You can only expect to get accuracy of around 6 to 10 meters by using a standard low-cost GPS system and that can be further downgraded by poor signal strength inside buildings. Bluetooth and WiFi positioning can achieve 1 to 5 metres resolution but that’s often not enough. The Pozyx system has been developed to achieve a positional accuracy of 10 cm and works indoors or outdoors.

Four ‘Anchor’ transceiver units attach to walls or fences surrounding the space in which the Pozyx Shield operates. Communication between the shield and the four anchors allows the shield to determine its position and orientation within its operational area.

Samsung gets serious about the IoT

20150518005630_Artik-2

by elektormagazine.com:

At the ‘Internet of Things World’ event held in San Francisco, Samsung Electronics announced three boards making up their new ARTIK development platform targeted at the Internet of Things (IoT) applications. To make the platform more attractive for developers it is compatible with the existing Arduino software development system. Young Sohn, President and Chief Strategy Officer of Samsung Electronics and Massimo Banzi, Co-founder of Arduino shared the stage to make the announcement.

The ARTIK 1 at 12mm square is the smallest board and includes a Dual Core processor running at 250 MHz and 80 MHz with 1 MB on-chip and 4 MB SPI Flash memory together with Bluetooth Low Energy (BLE) with Chip Antenna, secure element to give HW security and a 9-axis motion sensor. A single charge will allow the board to operate for three weeks while always-on and paired with a smartphone.

xPico WiFi SMT doesn’t require connector neither antenna

obr1706_1

High mechanical stability is one of benefits of a new „SMT“ version of the popular Lantronix xPico WiFi module.

Lantronix xPico WiFi module may be already familiar to you from our articles, for example: xPico WiFi is a dream come true for producers and customers where we also mention the HW compatibility with the xPico module ( wired, serial-to-Ethernet modul). New version – xPico WiFi SMT brings the same functionality as xPico WiFi and as the name saysm it´s intended for a direct soldering by an SMT (reflow) process, together with other components on a PCB. In contrast to original version which has an SMT (board-to-board) connector, SMT version is designed similarly like many GSM/GPS modules, i.e. as a module on a carrying PCB with soldering pads on PCB sides (half-vias, plus gnd on a bottom).

At the same time, SMT version is also available with integrated small ceramic antenna, so no external antenna is required. Just this version XPCW1003100B we keep as a standard stock item. Perhaps the biggest advantage of SMT version is this possibility of a direct soldering bringing a very high mechanical stability – also suitable for applications with a higher risk of vibrations.

xPico WiFi SMT is the same powerful („device server“) as a previous version and offers easiest way how to add WiFi connectivity into a target device, practically without a necessity to write a single line of code.

Simultaneous AP (Access Point) with a DHCP server and Client mode also enable a direct access – communication with other WiFi device, for example with a tablet or a smartphone.

Detailed information will provide you the xPico WiFi SMT brochure, xPico WiFi SMTi datasheet and the xPico WiFi SMT integration guide.
