ESP8266-01S with Relay

• Affordable Sparset, with the included Relay.
• Great coverage by Wi-Fi 802.11 b/g/n Standard.
• Universal application possibilities thanks to the three available operation modes: Wireless Router (AP), Wireless Client (STA), as well as both at the same time (AP + STA)!
• Thanks to a powerful 80MHz processor and a large 1MB memory, can be operated with the esp8266 01 also Autonomous!

When the module on the WIFI module is unplugged, USB to TTL module RX, TX, GND pins were connected to the module RX, TX, GND pin, IN +, IN- 5V power supply, then the module can be used as a USB Relays to use, scalability.

ESP8266 module has a timeout mechanism, when the phone for some time (the default 180S) did not give instructions to the module, the module will kick off the phone, the computer can send AT + CIPSTO = to modify this time (Time range 0-7200), such as: AT + CIPSTO = 3600 Mobile phone equipped with WiFi module Mobile phone and WiFI module equipped with the same router, through the mobile phone APP to control the relay; this mode, the transmission distance depends on the signal router.
