The proximity function offers plug and play detection to 100 mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly. The proximity detection feature operates well from bright sunlight to dark rooms. The wide dynamic range also allows for operation in short distance detection behind dark glass such as a cell phone. In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements providing very low average power consumption.

The ALS provides a photopic response to light intensity in very low light condition or behind a dark faceplate Features ALS, IR LED and Proximity Detector in an Optical Module • Proximity Detection – Fully Calibrated to 100 mm Detection – Integrated IR LED and Synchronous LED Driver Connection Code Links. X-Project (ESP8266 & ESP32) Starter Kit. Although makers/hackers/DIY enthusiasts have been around since man invented the wheel — or perhaps even before — it seems that a big part of what’s fueled the current crop of home invention has been inexpensive development boards like those developed by Arduino.

X-Project (ESP8266 & ESP32) Starter Kit

In fact, if you’re going to make a simple robot or automatic device, Arduino products, specifically the Arduino Uno acts as a sort of de facto standard. ESP32 CAN CAN board!! from microwavemont on Tindie. IOT Expert - Engineering for the Internet of Things. From Kickstarter to Home Depot: Edyn smart garden sensor brings IOT to your garden. The emerging Internet of Things (IOT) is enabling the use of smart devices, such as Edyn, in surprisingly down-to-earth places.

From Kickstarter to Home Depot: Edyn smart garden sensor brings IOT to your garden

And because this crowdfunded smart garden gadget is now available on the shelves of one of the biggest home improvement stores in the U.S., it's not just for early adopters anymore. One of the most entertaining parts of covering technology and gadgets is reading the press releases and pitches from startups that are convinced that they've built the next best thing, and which could really change the world... as long as changing the world consisted of turning your phone into a remote control for your lights, or turning your trash can into your grocery list maker.

The Edyn sensor is a solar-powered device that measures soil moisture, pH, temperature, humidity, light levels, and soil nutrient levels, in both real-time and over the long term, helping gardeners to accurately assess what their soil needs in order to support strong healthy plant growth. Computers + Electronics + LEGO. How to control a Window Blind using IOT enabled hardware (Part 1) This is part one of a series of articles where I will be showing you how to create a home automation system using Components and hardware which can be purchased from the RS Components website.

How to control a Window Blind using IOT enabled hardware (Part 1)

Also, we will show how you can build your own casing and gears on DesignSpark Mechanical. In this application, we will be controlling window blinds. Home Automation Project Details: We will use a Cayenne application to send a signal to an Arduino UNO WIFI which will control the motor rotation, this will pull the blinds up or down. It’s not necessary to use an Arduino UNO WIFI as we have but also an Arduino Uno will do just fine for this project too. In this case, we must connect the Arduino UNO WIFI to our laptop for the whole time of the project, as cayenne uses a computer as the main communication point.

Tinkering with Technology – playing with possibilities. ESP8266 Web Server Tutorial (Code and Schematics) If you want to learn more about the ESP8266 module, first read my Getting Started Guide for the ESP8266 WiFi Module.

ESP8266 Web Server Tutorial (Code and Schematics)

In this project you’ll create a standalone web server with an ESP8266 that can toggle two LEDs. First, watch the video demonstration below Why flashing your ESP8266 module with NodeMCU? NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Arduino. ChromaTab — a Slick Little WS2812B LED Controller. Getting Started with NodeMCU Board Powered by ESP8266 WiSoC. Since ESP8266 is now so popular, I’ve recently bought a NodeMCU board to try it.

Getting Started with NodeMCU Board Powered by ESP8266 WiSoC

I selected this board because the latest version of the board is breadboard-friendly, integrates a USB to serial chip, and it can be powered by a simple USB to micro USB cable. I also noticed a ESP8266 tutorial with NodeMCU firmware by SwitchDoc Labs the other day (using ESP-12 and Adafruit Huzzah), which I applied to my NodeMCU board, but since I encountered a few issues, I decided to report my findings, and write my own little getting started guide to switch on/off LED and GPIOs using a web interface. NodeMCU v0.9 and NodeMCU v1.0. Hackerspace / ESP8266. Some of this info is available elsewhere on the web, some is (as far as I know) not documented elsewhere.

September 21, 2016 AT 11:25 am NEW PRODUCT – Espressif ESP32 Development Board – Developer Edition The ESP8266 started a small revolution by bringing WiFi to a small and cheap package that also had enough processing power and enough pins to get small things done.

Favorited Favorite 3 Last year, the ESP8266 took the embedded IoT world by storm. For less than $10, you could get a programmable, WiFi-enabled microcontroller with just enough GPIO to wiggle some LEDs and monitor some sensors. I spent a good chunk of the year working with the chip – laying out a handful of boards, and mostly wrestling with the lightly-documented SDK (to put it nicely). WeatherBug: ESP8266 WeatherStation with IFTTT and HomeKit support. I assume you're familiar with Daniel Eichhorn's ESP8266 Weather Station.

I modified it to do a little more. Hardware changes Used a WeMos D1 mini with the DHT shield Software changes. ESP8266: Weather Station V2 Code published. This is a total make over of the earlier weather station. Instead of building my code on the NodeMCU lua firmware I decided to switch to the Arduino IDE based development setup. The reason for this was the constant problems with heap memory running out and other instabilities. When I finally found code that demonstrated the use of my beloved SSD1306 based OLED 128×64 displays the final piece was in place. I tried to separate the building blocks of the code into different classes, so they can be reused easiley for other purposes.
