5V 1 Channel Wifi Relay Card
5 Volt 1 Channel Wifi Relay Card. It is a module with one relay on it. There is a 5 volt signal input pin for controlling the relay on the card. The key status can be adjusted by relaying the signal from here. Thus, both AC and DC currents can pass through it.
When the ESP8266 module does not instruct the phone (default 180S) for a while, the module starts up the phone, the computer can send AT + CIPSTO = to change it (time interval 0 - 7200), for example: AT + CIPSTO = 3600.
When the module on the WIFI module is removed, the RX, TX, GND pin, IN +, IN-5V pins are connected to the power supply via the USB TTL module and then the module can be used as USB. The relays to be used can be scaled.
A mobile phone equipped with a WiFi module;
The mobile phone and the WiFi module, equipped with the same router, control the relay via the mobile phone APP. This mode is dependent on the transmission distance signaling router.
Note: Exclude the ESP8266 Module!
