Keyestudio Quick Connectors Ultrasonic Module(CS100A Chip/Black/Environment-friendly)

The Keyestudio Quick Connectors Ultrasonic Module is a high-performance, low-cost distance sensor designed around the CS100A chip. Operating on a wide voltage range from 3.3V to 5V, it is an ideal choice for students, makers, and educators building obstacle-avoiding robots or security systems.

Reliable distance measurement

The module measures distances from 4cm up to 300cm with high accuracy and stability. This makes it highly effective for robotics navigation, anti-theft devices, and custom distance-sensing applications.

Flexible power compatibility

With a wide working voltage range of 3.3V to 5V DC, this sensor integrates seamlessly with both 3.3V microcontrollers and standard 5V development boards. It typically draws a working current of 65mA during operation.

Standard pin interface

Featuring a standard 2.54mm 4-pin interface, the module is easy to connect to your breadboard or custom PCB. It utilizes a 10-microsecond TTL pulse trigger input signal and outputs digital signals for straightforward programming.

Focused detection angle

Operating at a frequency of 40KHz, the sensor provides a narrow 15-degree measurement angle. This focused detection cone ensures precise targeting and reduces false readings from surrounding obstacles.

Compact and lightweight design

Measuring just 49mm by 22mm by 19mm and weighing only 9.2g, this environment-friendly black module fits easily into tight chassis designs. It is lightweight enough for small mobile robots where payload weight is critical.
