Panel Mount Ultrasonic (Sonar) Ranging Module with UART Output
All prices are VAT included
This sleek-looking 'button' is actually an ultrasonic sensor, ready for panel mount use. Inside is a module that uses high-frequency signals to determine distance to a surface. It's elegant looking and is more durable than the 'raw' ultrasonics we sell a lot of, so it would do well in a garage, robot, or installation where you want a durable dust and weather-resistant design. It has a range of 28 cm to 450 cm with a read resolution of 1mm (precision is 1 cm).
This sensor has UART output, so it can connect to a microcontroller or microcomputer with a TTL serial port. You can also connect it to a computer using a USB-to-serial adapter and read data from the operating system's COM or serial port device.
It comes with a 2mm pitch connector you can cut off or re-purpose. To use, simply connect the red wire #1 to 5V, black wire #2 to ground, skip #3 and connect #4 to your serial input pin and read the data in at 9600 baud. Check out our Arduino and Python example code to get readings in a jiffy!
This sensor has a 'blind' zone distance of 0 to 28 cm, which means it can't accurately tell when something is less than that distance away . it's best used when you know that the object you're sensing is at least 30 cm from the sensor!
We carry a large variety of distance sensors here if this fellow isn't what you're looking for.
