RCWL-1603 超聲波測距感測器模組 支援多種輸出 串口 PWM GPIO 輸出 帶溫補
The RCWL-1603 is an open ultrasonic ranging module with 3V-5.5V power supply. It contains a variety of working modes including UART, GPIO, PWM and UART AUTO OUT. Its temperature supplement adopts MCP9700 professional temperature measuring chip.
Features:
1>. 3V-5.5V wide voltage power supply.
2>. Ultra-wide measurement range of 2cm-500cm (measurement of flat wall).
3>. UART, GPIO, PWM and UART AUTO OUT.
4>. Provide temperature output (UART mode only).
5>. Standby mode (UART mode only).
6>. Temperature compensation.
7>. The SWIM interface of STM8S003 is set aside for module up grade.
8>. Lead-free process.
9>. Adopt the general environmental protection probe, can customize the use of high – quality reinforced environmental probe.
10>. Working temperature: -20 Celsius to 90 Celsius
