Using a relay with the ESP8266 is a great way to control AC household appliances remotely. This tutorial explains how to control a relay module with the ESP8266 NodeMCU. We'll take a look at how a relay module works, how to connect the relay to the ESP8266 and build a web server to control a relay remotely (or as many relays as you want). Description This WiFi relay based on AI-Thinker ESP-01/ 01S WiFi module, we use the GPIO0 of ESP-01/ 01S to control the relay by low level. It's easy to DIY your smart switch to any device by your phone anywhere with this smart relay. Specifications Working voltage: DC 5V-12V Working current: ≥250mA Communication: ESP01 or ESP 01S

Bei. When we use an ESP8266 or ESP32 microcontroller with an operation voltage of 3.3V, we have to use the VIN or 5V output from the USB connection as power supply for the relay module and power the ESP8266 or ESP32 board via USB. The following picture shows the wiring between the most used Arduino, ESP8266 and ESP32 microcontroller and a relay module.

Step 1: Materials ESP8266 WiFi module Arduino Pro Mini 8Mhz, 3.3V 5V Relay module NPN transistor 2N2222 resistor 5K1 AMS1117 3.3V regulator 1000uF capacitor EasyIoT server ( Raspberry Pi or Windows machine) WiFi network (WiFi router) Buying guide for materials: http://iot-playground.com/blog/2-uncategorised/16-esp8266-wifi-relay-switch The objective of this post is to explain how to use the ESP8266 to control a relay. Since we are going to control the relay with a digital pin of the ESP8266, we need to use a device that can operate with 3.3V. Fortunately, eBay offers a wide variety of relays suitable to be controlled by a microcontroller, as can be seen here. Control Relay with ESP8266 01 Module This project shows how to control a relay with ESP8266. Intermediate Protip 30 minutes 11,071 Things used in this project Story Ideation There are many such videos out there on YouTube, but most of the people have used Relay modules instead of only a relay. Do you know the reason why? The ESP8266 can be controlled from your local Wi-Fi network or from the internet (after port forwarding). The ESP-01 module has GPIO pins that can be programmed to turn an LED or a relay ON/OFF through the internet. The module can be programmed using an Arduino/USB-to-TTL converter through the serial pins (RX, TX).

The circuit above have an AMS1117 IC and two capacitors. handles for receiving the input voltage of +5V and regulating it to a voltage level of +3V3. The figure 7 shows the IC on the printed circuit board. Figure 7 - +3V3 Voltage Regulator Integrated Circuit. Now, we will introduce the ESP8266 CHIP circuit block. In unserem eBook für den ESP8266-01 mit Relais haben wir euch erklärt, wie ihr mit den AT befehlen und einem Serial Terminal Programm das Relais schalten könnt. Heute möchten wir euch hier zeigen, wie das mit einer Website funktioniert. Am Ende haben wir 2 Buttons mit Ein und Aus. Legen wir los:
Project Schematic Diagram The circuit diagram for the project "Control a Relay using ESP8266" is shown in the image below. You can see that I've used a single channel relay module in the circuit diagram. Components Required ESP8266 Arduino UNO Resistors (1KΩ and 2.2KΩ) - both are ¼ Watt Resistors Jumper Wires Relay Module Small 5V Bulb Push Button I wanted to build a fairly simple project that combined a number of elements to further my skills. Mainly it was about creating a project to further develop my code writing skills for the ESP8266 in C code. Essentially, it is an 8-channel relay controller with a wifi interface and an auxiliary RS-232 port for connection to industrial equipment over serial. The PCBs are designed as a dual layer.

In Serial Monitor check if ESP module connects to AP. If connection is successful you will also see IP address of ESP8266. Remember this IP address. Connection. Connect ESP8266 GPIO2 pin to 5V relay module IN. Because relay module operats on 5V and ESP8266 operate on 3.3V we will use 2N2222 NPN transistor to shift levels. Grund is common for 5v. noiasca May 25, 2021, 10:47am 2 mindestens diese Punkte fehlen: mach einen groben Schaltplan auf Papier, fotografieren, hier hochladen.
