Sensor de distância a laser ESP32: Como conectar e o que você pode construir
Visão geral
In the world of IoT and embedded development, the ESP32 laser distance sensor combination stands out as a versatile and cost-effective solution for real-time distance measurement. Whether you’re creating a smart parking assistant, a robot navigation system, or an industrial monitoring device, pairing ESP32 with a laser sensor gives you speed, accuracy, and wireless control — all in a compact setup.
In this article, we’ll walk you through how to connect the ESP32 with different types of laser sensors, show example code, and explore what kind of applications you can create with this versatile setup.
What is ESP32 and What Can It Do?
O ESP32 is a powerful, low-cost microcontroller developed by Espressif Systems. It features:
- Dual-core 32-bit processor
- Wi-Fi and Bluetooth (Classic & BLE) built-in
- Multiple GPIOs, UART, I2C, SPI, PWM, and ADC interfaces
- Low power consumption modes
- Support for cloud connection and OTA (Over-the-Air) updates
Thanks to its wireless capabilities and strong community support, the ESP32 is ideal for IoT projects, sensor integration, real-time data logging, and automation systems.
Why Combine ESP32 with a Laser Distance Sensor?
When combined with a sensor de distância a laser, the ESP32 becomes a smart measurement platform. A laser sensor offers millimeter-level precision, fast response time, and long-distance range. This makes the esp32 laser distance sensor setup perfect for applications like:
- Robotics and drone navigation
- Obstacle detection and proximity alerts
- Industrial automation and safety zones
- Smart home devices (e.g., measuring door/window positions)
- Tank level monitoring and warehouse logistics
What You’ll Need
To build an ESP32 laser sensor system, prepare the following hardware:
- 1x ESP32 development board
- 1x Laser distance sensor module (e.g., Sensor de distância a laser LDL , or Sensor de telêmetro a laser TS1224)
- Jumper wires
- Breadboard (optional)
- Power source (3.3V or 5V depending on the sensor)
Wiring Guide: Connecting ESP32 to Laser Distance Sensor
For I2C Laser Sensors :
- VCC → ESP32 3.3V
- GND → ESP32 GND
- SDA → ESP32 GPIO21
- SCL → ESP32 GPIO22
For UART Laser Sensors :
- VCC → ESP32 5V
- GND → ESP32 GND
- TX (Sensor) → ESP32 RX (e.g., GPIO16)
- RX (Sensor) → ESP32 TX (e.g., GPIO17)
For RS485 Industrial Laser Distance Sensors:
Use an RS485 to TTL converter, then connect the converter’s TX and RX to the ESP32 serial pins. RS485 allows for stable long-distance communication — ideal for harsh industrial environments.
Example Code: I2C with LDL
#include <Wire.h>
#include <Adafruit_LDL.h>
Adafruit_VL53L0X lox = Adafruit_LDL();
void setup() {
Serial.begin(115200);
Wire.begin();
if (!lox.begin()) {
Serial.println("Failed to start LDL sensor");
while (1);
}
}
void loop() {
LDL_RangingMeasurementData_t measure;
lox.rangingTest(&measure, false);
if (measure.RangeStatus != 4) {
Serial.print("Distance (mm): ");
Serial.println(measure.RangeMilliMeter);
} else {
Serial.println("Out of range");
}
delay(500);
}
What Can You Build with an ESP32 Laser Distance Sensor?
Here are some real-world applications of an esp32 laser sensor setup:
