Ультразвуковой датчик расстояния
1. Product description:
RCWL-1005 is a transceiver integrated ultrasonic ranging module designed by our company's self-developed chip RCWL-9624.
By default, the software is fully compatible with our old version HC-SR04; it can be set to UART, IIC or single-bus mode through resistors. 25CM ultra-small blind area, 4.5M typical farthest ranging, 2mA ultra-low working current. The self-developed chip RCWL-9624 is used to make its periphery simpler, wider operating voltage (2.8-5.5V), and more interface functions.
2. Main features:
•Adopt professional chip RCWL-9624
• Working voltage: 2. 8-5V
• Working current: 2mA
• Support GPIO, UART, IIC and -WIRE multiple outputs
mode, the default output mode is compatible with HC-SR04
• 50mS period
Typical application:
• Toys, robot obstacle avoidance
• Liquid level, water level measurement
• Other ranging applications
