To do so, we will use COM pin and NO pins of high voltage side of relay. Because we want to light up the bulb with active high signal. We will be using normally open configuration in this project. Now make this layout on breadboard according to the connection diagram shown here: You are using HIGH voltage in this project, please take all precautions before making this layout. Warning: Before making this circuit diagram, make sure you have not connected ESP32 and lamp with power supply.
Power supply connector Connection diagram of relay and lamp with ESP32. You will require following components to build ESP32 remote control relay project: Through which type of signal, you want to turn on or turn off relay. So, you can choose either pin according to active high or low signal. Normally closed: if you use normally close pin, active low signal activates the relay and active high signal on signal pin will deactivate the relay. Normally open: If you use normally open pin, relay will activate with active high signal on control pin and active low signal turn off the relay as shown in figure below: Depending on NC or NO, you will use active high or active low signal to control the relay. You always use common pin and either normally open pin or normally close pin to connect load. There are two contact pins that are normally open and normally closed. It makes the circuit complete and load turns on. When we apply active high signal at the signal pin from any microcontroller like ESP32, relay contact move from normally open to normally close. Table given below provides details on functionality of each pin Pin Name Pin function NC Normally closed terminal (120-240V) NO Normally open terminal (120-240V) Common Common terminal to connect one led of load Vdd 5V pin (connect with ESP32 Vin pin) Ground Connect with ground pin of ESP32 Signal pin Control pin for relayĪs shown in relay module picture, it also has other components and relay in the middle of board. electrical loads and 220 volts power supply and other three pins are used for low voltage side namely vcc, ground and control signal pin. 
Three pins are used to connect with high voltage side i.e. It works on and can be used to control output loads from 120-240 volts and current range of 10A. However, I will be using SRD-05VDC-SL-C 5V Relay module. ESP32 will give signal to relay depending upon the button state from a web page. We will use a button on web page to control a relay. You will use a relay as a switch to control 120-220 volts lamps. We have to use a relay between ESP32 and lamp. We can not interface these AC loads directly with ESP32 development board. Light bulbs usually operate on 120 volts or 220 volts power supply in case of AC main supply.

How to control 5 volts relay with Arduino Why we need to use relay?. Introduction to Electromechanical relays. You can read these articles to gain further details on relays and their working. 
When coil fully energized, contact shift from normally open position to normally close position. When we supply dc voltage across the coil, it starts to energize. We generally apply dc voltages to coil and connect load across normally open and close contacts. Relay is an electromechanical device that is used as a switch between high current and low current devices. Video demo Introduction to a relay module.How to access Web Server to control lamp.
Controlling relay module remotely with ESP32. Connection diagram of relay and lamp with ESP32. For instance, you can change the settings of the user device through LAMP, as shown in the image below. These changes are then pushed to the individual client devices.Īccess management, with its centralized control, boosts operational efficiency removing the need of managing the device manually. Basically, an admin would make changes inside the LAMP portal. This removes the need to manually and individually configure each device. The Access Management feature would give more control to an organization over their SAP environment for their mobile devices. It makes it easy to configure the App at a centralized location in the cloud and then deploy the configuration remotely. This feature provides an organization a centralized way to manage their devices. Furthermore, it also enables configuring the App settings, including installing a license, adding an SAP connection, and more, over the cloud. #Android web server lamp license#
Liquid UI introduced a new feature called Access Management for Enterprise users (where your Android/iOS App license is managed using Liquid UI Management Portal).
