ESP8266 ESP-01 5V, 1 Channel WiFi Relay, Module Things Smart, Home Remote Control, Switch

• Relay Specifications: 1 channel relay capable of handling up to 250V AC and 30V DC, suitable for activating remote lights or other systems.
• Status Indicators: Includes an LED that indicates the state of the module. A red power activation LED lights up when a signal is received on the IN pin.
• Audible Feedback: The relay emits an audible click when it triggers, providing clear feedback of the activation.
• ESP8266 Integration: Controlled via the onboard ESP8266 module, which requires configuration via UART before full operation. Once configured, it operates independently, making it ideal for IoT projects.

• STA (Client): Connects to an existing WiFi network.
• AP (Access Point): Creates a WiFi network for other devices to connect.
• STA + AP (Client + Access Point): Operates both as a client and an access point.

Configuration:

• Setup: Use serial debugging software and a USB to TTL module to send AT commands for configuring the WiFi module. Connect the USB to TTL module to the module's TX, RX, and GND pins, and provide a 5V power supply.
• Note: The product design may vary.

• Diode Protection: Includes diode effusion protection to safeguard the module.
• Short Response Time: Provides fast response for quick relay activation.

• Remote Control: Operate devices or systems remotely via a mobile app.
• Home Automation: Integrate into IoT projects for controlling home appliances.
• Industrial Control: Use for remote switching in industrial settings.
