keyestudio ESP-01 3V Relay Module(Black and Eco-friendly)



Description

Relays are one of the most commonly used components for setting the smart home when we are doing the Internet of Things.
For wireless control, we specially designed this relay module. The relay module is equipped with an ESP8266-01 Wifi module.
It can be connected to the wireless network, and then can send commands to the module in the remote or LAN host computer. After receiving the command, the module can close or open the relay.

2.Station Mode Operation

Because the station_server IP is automatically assigned by the router, so need to read the IP from the serial port. For example:
Set the SSID of the home Wifi to: KeyesWifi_S and password is KeyesWifi
(note here should set your own home wifi)

Directly connect the keyestudio USB to ESP-01S Wifi shield to your computer’s USB port. Then push the shield’s button to Flash Boot side.

Open the PUTTY software on your computer. Below is the example figure we operate.

thumb

Double-click the icon of PUTTY software, pop up the interface window below.
thumb

After Click Open, plug the ESP8266 WIFI module into keyestudio USB to ESP-01S Wifi shield.
Note must click Open first, then plug the ESP8266 WIFI module into keyestudio USB to ESP-01S Wifi shield. Or else it is invalid.

The PUTTY terminal will print the message showed below. IP read success!

thumb

From the figure, remember your IP name, here is 192.168.3.5


 The computer and the home wifi are in the same LAN, and the network segment is the same. Connect your computer to your home WiFi. For example, here we use: SSID: KeyesWifi_S  ; Password: KeyesWifi


 Plug the ESP8266-01 module into the relay module and access to 3.3V power supply.

thumb


Open the network debugging assistant software, as shown below.

thumb

thumb


 Send the signal PIN00=0 to close the relay. Shown below.

thumb

You will hear the tick sound of relay closed.


 Send the signal PIN00=1 to open the relay. Shown below.

thumb

You will hear the tick sound of relay open.
For the Station mode operation, the test is finished!



3.Softap Mode Operation


 The computer and the home wifi are in the same LAN, and the network segment is the same. Change your home wifi name to avoid wifi module automatic connected.

 Connect your computer to your home WiFi. For example, here we use: SSID: KeyesWifi_A  ; Password: KeyesWifi

 Plug the ESP8266-01 module into the relay module and access to 3.3V power supply and wait for 20 seconds.

thumb

 Open the network debugging assistant software, as shown below.

thumb

thumb

 Send the signal PIN00=0 to close the relay. Shown below.

thumb

You will hear the tick sound of relay closed.

 Send the signal PIN00=1 to open the relay. Shown below.
