TTL distância do laser sensors have become one of the most widely used medição sem contacto solutions in embedded systems, IoT devices, and OEM industrial modules. Their compact size, low-voltage TTL interface, and millimeter-level accuracy make them ideal for developers who need stable, real-time medição de distâncias without the complexity of heavy communication protocols.
Meskernel’s TTL-output laser sensor de distância series—such as the LDL-P, LDL-P4, and long-range OEM alcance laser modules—are engineered for high-precision applications in drones, robotics, automation, and smart devices.
What Is a TTL Interface?
TTL (Transistor–Transistor Logic) is a low-voltage serial communication level commonly used in microcontroladores, embedded modules, and digital circuits. Unlike RS232 or RS485, TTL signals operate at 3.3V or 5V, making them ideal for direct MCU integration.
Key characteristics:
- Voltage levels typically between 0–5V or 0–3.3V
- Simple wiring (TX, RX, GND)
- Direct compatibility with most development boards
- Less power consumption compared to RS232/RS485
TTL communication is especially popular in Arduino, ESP32, STM32, Raspberry Pi, and custom OEM boards where space and power efficiency matter.
