About Your Device #
The PULSE sensor utilises time-of-flight technology to provide accurate spatial data. It includes a transceiver (Tx) and receiver array (Rx) integrated on the front face for efficient signal transmission and reception. Data transfer is handled through the USB Type-C port on the back of the device, ensuring high-speed communication with minimal setup.
For easy installation, the device features two (M3) mounting screw holes located on its rear panel, allowing for secure attachment during setup. The PULSE sensor is designed for precision and ease of use, making it a reliable component in any 3-D spatial sensing application.

⚠️ Device Safety #
To ensure safe and effective use of your sensor, please follow these important safety guidelines:
- Avoid Ear Proximity: Do not hold the sensor close to anyone’s ears, as the ultrasonic pulses could cause discomfort.
- Placement During Operation: Do not place the sensor face down on any surface while it is powered on.
- No Disassembly: Do not attempt to open or disassemble the device, as it may cause damage or void the warranty.
- Handle with Care: Avoid dropping or mishandling the sensor to maintain its accuracy and longevity.
- Power Requirements: Only connect the device to a computer or compute resource that provides a regulated 5V power supply.
