Product Description

The purpose of this design is for learning how to play with the hardware and software of a IOT project, it is based on price competitive wifi module ESP8266.

Hardware Features

  • Based on ESP-12F ESP8266 Wifi Board
  • This relay board use one AC input, and supports two relay AC output. Please note the output AC power comes/connected from/with input AC power. Relay only play as on/off switch for AC power. Will be danergerous to use in any other cases.
  • Use mature AC-DC power module, input volatge 85 – 265VAC
  • Relay Specification:
    • HF46F-5-HS1, 5A250VAC, 5A/30VDC
  • Plastic enclosure design support, package includes the PCB board, plastic case, and self-drilled screws (screws are not assembled). Case general dimension is 111*42 mm.
  • Two Lead out buttons BTN1 and BTN2
  • Two relay indication LEDs
  • One status LED, indicating connecting status in demo code
  • A few lead out pins, from top (left) to bottom (right):
  • Resevered design for temperature sensor DHT22
  • Screw terminal which are easy for wiring output.

Demo Software Features

  • Programming skills need, not recommended for unfamiliar user.
  • The board flashed with demo test code, you can follow the youtube video to make a try directly. And find demo code in the wiki page below. Only nodemcu demo code avaialble.
  • The demo code written in R1.1 will do:
    • switch both relay on/off once per second, and wait for smart config
    • When connected to local wifi by smart config, on/off switching relay will stop and you can use mqtt to control it, follow wiki instruction for further details.
  • You can use USB-TTL debug to re-program it. 
  • If you want to customize it, please contact via info@electrodragon.com
  • Use MQTT platform called www.cloudmqtt.com, use-friendly for esp8266
  • Based on NodeMCU LUA coding
  • Demo code available, open source, and support smartconfig and MQTT, please find the code below or at our dropbox page to download

Note:

  • The board has exposed high voltage AC connection, be very carefully on this.
  • Please notice the two relay output terminals are a little conflict with case, second channels need to use soft wires or remove the screw installation bars manually.
