Numato Lab 4 Channel Ethernet Solid State Relay module allows controlling electrical devices remotely through Ethernet. This is very helpful in those situations where the device that needs to be controlled is located far from the PC and thus can not run USB cable. Numato Lab Ethernet Solid State Relay modules are designed to be very easy to set up and use.
This product has 4 onboard Solid State Relays and 10 GPIOs. Each relay/gpio can be individually controlled through the built-in easy to use web interface or through any popular terminal emulator that supports TELNET protocol. Each 4 Channel Ethernet Solid State Relay Module is shipped with a unique MAC address. These devices also support assigning and retrieving custom identification string that can be used for identifying individual devices when there is a large number of devices connected on the same network. All relay terminals are available on screw terminals which makes connecting external devices very easy.
Features
- 4 onboard Solid State Relays with individual LEDs for status.
- 3A Maximum Switching Current.
- 10 TTL (3.3V)Compatible GPIOs.
- 10 Analog Input Channels (Multiplexed with GPIOs).
- 10 bits Analog Input Resolution.
- Password-protected Web console and Telnet communication interface.
- LED indication for Power and individual relay status.
Applications
- Home Automation
- Industrial Automation
- Lighting Control
- Garden Equipment Control
- Test Fixtures
- DIY and Hobby

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.

A Visitor Counter automatically counts the number of people entering or leaving a room using an IR sensor. The count is displayed on a 16×2 LCD, and a buzzer can alert when a specific limit is reached. This project is widely used in shops, libraries, offices, and events to monitor occupancy. It demonstrates sensor interfacing, counting logic, and real-time display using Arduino.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

- A rain alert system with an LCD display and buzzer, controlled by an 8051 microcontroller, is designed to detect rainfall and provide real-time notifications. The system uses a rain sensor to detect moisture or rainfall, and the microcontroller processes the sensor data. When rain is detected, the 8051 triggers a buzzer to alert the user audibly and displays the rain status on an LCD screen.
