DETAILED DESCRIPTION
In this project, you will learn how to do basic electrical automation and control via the web. Think of the NEST.... only more open and hackable! Using Websockets, Javascript and HTML5, you will have a simple way of viewing remote data and be able to control some solid state relays. This framework will allow you to create more complex IoT applications. The example will combine a FRDM-K64F and a FRDM-AUTO to read a temperature sensor and control a solid state relay.
Skills Developed:
- Embedded Systems Networking
- Electrical Control Systems
- HTML5/Javascript - Websockets
- SOIC8 and 1206 Surface mount soldering
- Internet of "Things"
FRDM-AUTO Features:
- QTY 1 High Current Solidstate Relay - Sharp S116S02F - 16A Zero CrossTriac output SSR
- QTY 1 Low Current Solidstate Relay - Sharp PR3BMF51NSKF - 1.2A Non-Zero Cross type Triac Output
- Convenient Terminals for connecting ring/fork terminals to power circuits.
- QTY 2 Opto-Coupled Inputs - MOCD207
- MCP9700 Termperature Sensor
- RN-XV Serial to Wifi Interface
- Optional RS-485 Interface
- Optional MAX31855K Thermocouple to Digital Converter with Omega PCC-SMP-K thermocouple connector
There are lots of project videos to learn from. The videos are organized into a nice YouTube playlist:
- FRDM-AUTO Hardware Overview
- MonkeyDo Software Overview
- Websockets & The MonkeyDo communication model
- Solid state relay introduction & sage
- Opto-coupler introduction & usage
- MonkeyDo system demonstration
When you get started, do NOT hook up anything to the solid state relays until you are sure things are working.
WARNING: Wiring to household power can be dangerous! You are 100% responsible for what you do. Be careful and never apply power until you fundamentally understand what you are wiring up!
Go forth and automate.
