ESP8266 ESP-01S 5V WiFi Relay Module for Smart Home

Description: ESP-01 Advantages: low price, only to earn a small profit base, hope that this will bring more rapid development of the Internet of Things smallest, the size of a fingernail. Easily embedded into any product Powerful internal ran LWIP agreement supports three modes: AP, STA, AP + STA coexistence mode perfect simple and efficient AT commands, allowing you to develop more simplely ESP-01S Parameters: Wireless standard: 802.11 b / g / n Frequency range: 2.4GHz~2.5GHz(2400M ~ 2483.5M) Data interface: UART / HSPI / I2C / I2S / IR Remote Contorl / GPIO / PWM Operating voltage: 3.0 ~ 3.6v (Suggest 3.3v) Working current: average 80mA Operating temperature: - 40 degrees to 125 degrees Storage temperature: room temperature Package size: 14.3mm * 24.8mm * 3mm External interface: N / A Wireless network mode: station / softAP / SoftAP + station Security mechanisms: WPA / WPA2 Encryption type: WEP / TKIP / AES Upgrade firmware: local serial port burn, cloud upgrade, host download burn Software development: support customer custom server, provide SDK to customer secondary development Network protocols: IPV4, TCP / UDP / HTTP / FTP User Configuration: AT + instruction set, cloud server, Android / IOS APP Pin Definitions: GND: GND GPIO2: General purpose IO, internal pull-up GPIO0: Operating mode selection: floating: Flash Boot, operating mode Dropdown: UART DownLoad, download mode RXD: serial port 0 data end RXD VCC: 3.3v, the module power supply RST: External reset pin, low reset, can be left floating or external MCU CH_PD: Chip enable, high enable, low level disable TXD: serial port 0 data end TXD WIFI Relay Module This module is based on ESP-01/ESP-01S and is remotely controlled by mobile APP for use in smart home or IOT projects. Module Parameter: Working voltage: DC 5V-12V Relay load capacity: 10A 250VAC 10A 125VAC 10A 30VDC 10A 28VDC Size: 37.3*25.6mm M3 mounting hole VCC, GND supply positive and negative, the mother is ESP-01/01S interface, the button is the reset button NC relay normally closed, COM relay common, NO relay normally open Instructions for use: Use the ESP-01/01S one-click downloader to download the Arduino sample program for the ESP-01/01S module and open the Arduino serial monitor to view the IP address. Insert the ESP-01/ESP-01S into the 2*4 Pin female, as shown below: Power supply to VCC GND (2.54mm pin header) Connect the computer or mobile phone to the router (same router as the ESP-01S), open the browser, input the IP address printed on the serial port, and then control the relay to release.
