How to Use sinaleira vermelha: Examples, Pinouts, and Specs

The Sinaleira Vermelha is a red traffic light used in traffic control systems to signal vehicles and pedestrians to stop. It is a critical component in ensuring road safety and efficient traffic management. The red light is typically part of a larger traffic light assembly, which includes green and yellow lights, and operates in coordination with other traffic signals.

• Urban traffic control systems
• Pedestrian crossings
• Railway crossings
• Industrial safety signaling
• Parking lot management systems

For LED-based Sinaleira Vermelha, the pin configuration is as follows:

Note: For AC-powered models, the control pin may not be present, and the light is controlled via a relay or switch.

1. Power Supply: Ensure the correct voltage is supplied to the Sinaleira Vermelha. For DC models, connect the VCC pin to a 12V DC power source and the GND pin to the ground. For AC models, connect to a 220V AC power source.
2. Control Signal: If the model includes a control pin, connect it to a microcontroller (e.g., Arduino) or a relay module to toggle the light ON or OFF.
3. Mounting: Secure the traffic light in a weatherproof enclosure or mount it on a pole for outdoor use.
4. Testing: Verify the light's operation by applying power and sending control signals.

• Voltage Compatibility: Always check the operating voltage of the specific model before connecting it to a power source.
• Heat Dissipation: Ensure proper ventilation around the light to prevent overheating, especially for incandescent models.
• Weatherproofing: Use models with an IP65 or higher rating for outdoor installations.
• Polarity: For DC models, ensure correct polarity when connecting the power supply to avoid damage.
• Safety: Disconnect power before performing any maintenance or wiring changes.

Below is an example of how to control a 12V DC Sinaleira Vermelha using an Arduino UNO and a relay module.

• Connect the VCC pin of the traffic light to the relay's NO (Normally Open) terminal.
• Connect the GND pin of the traffic light to the relay's COM (Common) terminal.
• Connect the relay module's control pin to Arduino pin 7.

// Define the relay control pin
const int relayPin = 7;

void setup() {
  // Set the relay pin as an output
  pinMode(relayPin, OUTPUT);
  
  // Turn off the traffic light initially
  digitalWrite(relayPin, LOW);
}

void loop() {
  // Turn on the red traffic light for 5 seconds
  digitalWrite(relayPin, HIGH);
  delay(5000); // Wait for 5 seconds
  
  // Turn off the red traffic light
  digitalWrite(relayPin, LOW);
  delay(5000); // Wait for 5 seconds
}

Note: Use a suitable relay module that can handle the current and voltage requirements of the traffic light.

1. Can I use the Sinaleira Vermelha with a solar power system?

   • Yes, as long as the solar system provides the required voltage and current.

2. What is the lifespan of the LED-based Sinaleira Vermelha?

   • LED models typically last up to 50,000 hours under normal operating conditions.

3. Can I use this traffic light indoors?

   • Yes, but ensure the brightness is appropriate for indoor use to avoid glare.

4. Is the Sinaleira Vermelha compatible with smart traffic systems?

   • Yes, it can be integrated with smart systems using microcontrollers or programmable logic controllers (PLCs).

By following this documentation, you can effectively use the Sinaleira Vermelha in your traffic control or signaling projects.
