Features

Serial Communication Interfaces

The TF3800 laser rangefinder module supports multiple serial communication interfacesincluindo UART, TTL, and optional RS232 ou RS485, allowing flexible integration into various systems:

• UART (Universal Asynchronous Receiver/Transmitter): Widely used in embedded systems for full-duplex communication with microcontrollers or PCs.

• TTL (lógica de transistor-transistor): Ideal for direct connection with low-voltage logic devices like development boards and single-chip microcontrollers.

• RS232 (optional): Common in industrial equipment and computers for longer cable communication and higher noise immunity.

• RS485 (optional): Suitable for long-distance and multi-device communication in noisy industrial environments.

These interfaces allow users to connect the TF3800 1535nm laser rangefinder module seamlessly to their host systems with minimal configuration.

Compatível com Arduino, Raspberry Pi e ESP32

The TF3800 is fully compatible with popular development platforms such as:

• Arduino: Perfect for hobbyists and prototyping; simply connect the UART/TTL interface to the Arduino’s serial pins to start collecting distance data.

• Raspberry Pi: Supports Python or C-based development; easily interfaces via the GPIO serial port for applications like mapping or obstacle detection.

• ESP32: Enables wireless data transmission using Wi-Fi or Bluetooth; ideal for IoT-based distance measurement and smart monitoring systems.

With provided communication protocols and wiring guides, developers can quickly integrate the TF3800 1535nm laser rangefinder module into their applications, from DIY projects to commercial embedded systems.
