Have you seen one of these
ESP01 Wi-Fi relay modules? It is an interesting piece of module
that is suitable for smart homes and internet of things projects.
Let’s take a closer look. As its name suggests, the major components
are an ESP8266 ESP01 module and a relay. The relay is connected to the GPIO0 pin of
the ESP01 through a PC817 opto-isolator chip. The relay's functionality can be
checked with a trigger switch, and its on or off state is indicated with an LED.
The COM, NO, and NC connections of the relay are available at this terminal block.
The module operates with voltages from 5 to 12 volts, regulated to 3.3 volts
for the ESP01 with the AMS1117 chip. You can remove the ESP-01 from
its socket for programming. Insert the ESP01 into the ESP01 programmer and
plug it into the USB port of your computer. See purchase link in the description. You can have a network of these modules
around your apartment as the basis for your home automation system to switch on and
off your lighting, heating, and lots more. We are going to make a custom mobile app program for the module to operate a light
bulb with RemoteXY and FLProg. First, start a new project on remotexy.com. Configure the connection as an access
point for the ESP8266-based board. Select the WiFi on-chip module and FLProg IDE.
Note the access point port number from here. Then, label the app as ESP01 relay. Add an edit field to delay the switching time of
the lamp with the integer input type selected. Add a push switch to switch on and off the lamp, set the draw type to rectangular, and
change the switch off caption to off delay. Add another rectangular push switch with
the switch on caption changed to ON delay. And a last rectangular push switch with the switch
captions changed to "blink on and blink off." Then click on "get source code" to
copy the code for use in FLProg. Create an ESP8266 ESP01 project in FLProg. Go to the controller WiFi module
settings to enable the access point. Input a network name of the ESP-01
relay and a password as required. Then add a digital output of
a relay assigned to GPIO0. Drag a remotexy block into the
program and double-click on it. Provide a connection password if required
and select the built-in WiFi module. Select the access point
and input port number 6377. In the inputs/outputs tab, click on "download description" and
paste the remotexy source code here. Observe that the remotexy three push switches and
the edit field are shown in the output section. And with their output
connections shown on the block. Add a timer block to the program and configure it
as a turn-off type with an external input delay. Configure another timer block as a
turn-on type with an external input delay. Also, configure a generator block as a symmetrical
multivibrator with an external input pulse length. Connect the remotexy push switch
outputs to the EN inputs of the blocks. And the edit output to the
val inputs of the blocks. Drag an OR block and the relay
output tag into the program. Right-click on the OR block
to add additional input. Connect the output of the timer
blocks to the input of the OR block and the output of the OR
block to the relay output tag. Then click on the upload button.
When the Arduino IDE is displayed, ensure that the Generic ESP8266 board
type and the port number are selected. Also, select the appropriate Flash Size and the
Reset Method of your ESP01 before uploading. Insert the ESP01 back into the relay module.
Connect one terminal of a light bulb to the NO terminal of the module, and to
220 volts of the AC neutral line. The common terminal should go to the AC live.
Then power up with a 5 to 12-volt DC power supply. Turn on your mobile WiFi and connect
to the ESP01 relay access point. Download the Remotexy app into your mobile phone.
Add a new device and select WiFi point. Input port number 6377 and select the ESP01
relay access point to connect to the module. With a zero-delay time, these buttons
will turn on and off the light bulb. When the delay is set in milliseconds,
the first button press turns on the bulb immediately but delays its
turning off for the specified time. The second button will delay turning on
the bulb, but turn it off immediately. While the last button will blink the bulb
with the specified on and off duration. Thanks for watching.
