Introduction  

"Backers... Thank you for backing our previous campaign..." ​From our previous successful​ly fulfilled​ Kickstarter ​experience and feedback we ​wanted to​ create​​ this ​advanced​ board which could be fun for ​t​inkerer​s​, ​hobbyists​ and g​eeks ​(like us!) ​to control appliances remotely using ​just your​ android phone or ​to ​connect sensors which will magically turn on/off lights​ and appliances making them 'smart'.​ ​​ ​

W​e ​present to you the "WiFi Quad Relay Board". An advanced version of our previous ESP8266 based WiFi ​enabled board with which also includes a 100-230V​ ​/5V AC​/​​D​​​​C power supply so that you will be able to connect it directly to AC mains​ - creating ​4 WiFi enabled smart devices at the same time​. It also has the node​ MCU​ ​compatible​ header where you ​can​ connect I2C based devices like an ​O​LED​ or sensors like PIR, IR, Temperature etc​....​ so ​yo​u can not only control four individual appliances but also add sensors and​ displays to make your home as 'smart' as you​ want.

We ​have​ also​ thrown in an onboard ​USB​ to ​UART​ converter which ​can ​connect to the ​ESP​8266 module and ​can be used to​ program the ​ESP​8266 ​to your​ ​liking​.

​W​e ​are looking for your support to improve the hardware and manufacture it. ​

Please ​support us by backing our project to make our simple​ and​ fun project successful.

Features & Specifications

  • Board consists of 100-240V AC to 5V DC converter
  • Four Relays to connect four AC/DC loads. Both NC/NO connectors of the relay are provided.
  • Can connect additional sensors like PIR, IR, Temperature, Humidity, Limit switch etc.
  • WiFi Quad Relay Board can be programmed as "MQTT Client" for Networking/Home automation integration.
  • SSID and Password can be set directly from the mobile phone web browser using default firmware.
  • LED for Testing which is connected to a GPIO and also as indicator when the relay go on /off.
  • Dimensions of the board are 145 X 60 X 22 mm.

WiFi Smart Strip

Making of WiFi Smart Strip by using WiFi Quad Relay Board and a plastic box (Dimensions 220*155 *60 mm)
Plastic box consists of 4 sockets, 4 Two way switches and a WiFi Quad Relay Board

What can we make with a WiFi Quad Relay Board

  • "WiFi Smart Strip" creating WiFi smart strip using the WiFi Quad Relay Board with 4 sockets & 4 two-way switches.
  • "Anti-Theft System" when motion is detected activate siren and close your door.
  • "Industrial Applications" where sequence of operations is perform based on  sensors data.
  • "Home Automation" to activate different appliances at same time or serially. (once you are awake switch on your heater, a washing machine, a Coffee machine).
  • "IoT PIR Sensor Board" (When motion detected it can activate buzzer and inform the user).
  • "A Temperature Logger" (Based on the temperature settings can activate the devices and inform the user).
  • "Tank Water Controller" (Based on the water level it can switch on motor and log the motor timings).
  • Using multiple Sensors like PIR, Temperature etc control different appliances parallely or serially. 

These are the some of the applications of WiFi Quad Relay Board.

Features WiFi Smart Switch Single Relay

  • Attiny 85 Microntroller 
  • The board can also connect other standard Bluetooth/Rf modules as the communication is UART based
  • WIFI Smart Switch can be programmed as MQTT Client
  • Can connect additional sensors like PIR, IR, Temperature, Humidity, Limit switch etc.
  • Has 5V/9V input and the Attiny85 can run at 5V or 3.3V depending on jumper position this will help while interfacing 5V sensors.
  • A Relay to control AC/DC Loads.

Just message us after backing. 


Shipping

For shipping we will be using standard International and Domestic postal service.

The People

We are a small group of professionals who like to develop easy simple boards to execute hobby projects. The group consists of both well experienced as well has young and dynamic people capable of handling projects from design to production. We have in our team multidisciplinary design engineers as well as professional production and quality control people. We assure you that we will see to that each of our project backer will be satisfied with our systematic approach and by our scheduled project product delivery. We also take up Hardware, PCB Design, PCBA Assembling, Testing & Software development work. If you have any such project which you wish to outsource you can contact us.

Where will the funds be used

  • Manufacturing of the Hardware.
  • Improved version of the present board.

Risks and challenges

Every project starts with understanding the risk involved in it . Some are anticipated risk and some surprise us. Having team members who have taken up projects individually and have executed them from design to production, we don’t think we will have any issue in solving the various problem that will be coming on our way. Furthermore, having some team members who specialize in production and quality control, we think we're well prepared and will execute the project without many hurdles and delay.Also we have successfully completed our first kickstarter campaign so we are now better aware of the risks and challenges.

Anticipated Risk.

· Feedback implementation in design delay

· Material delivery delays

· Quality Control and Testing Delay

· Shipment delivery Delay

Having mentioned a few we also do consider some risk which do get noticed when we are actually executing it but we assure you that we will put all our effort to solve it and deliver the reward to our backers
