<br />
== Technical overview ==<br />
* Core technology: time-of-flight measurement using 940 nm near-infrared light; distance is derived from the travel time between emission and reflection.<br />
* Measurement range 1 cm to 5 m with 1 mm resolution and a 10 Hz update rate.<br />
* Communication via UART or CAN (shared connector type); default baud rates are 921.6 kbit/s for UART and 1 Mbit/s for CAN.<br />
* Two output modes: active output (single module only, 10 Hz) and query output (usable in cascade setups).<br />
* Cascading support: up to 8 modules over UART and up to 7 over CAN; each module has a unique ID.<br />
* Adjustable field of view (FOV): 15° to 27°, offset -6° to +6°; smaller FOV improves short-range precision but reduces maximum range.<br />
* Power supply 3.7–5.2 V with reverse-polarity protection; power consumption approximately 290 mW.<br />
* Ambient-light resistance is limited (~10k LUX), so the sensor is primarily intended for indoor use; strong ambient light can degrade accuracy.<br />
* Distance status codes (e.g., 0 = valid, 14 = invalid) allow additional data processing beyond the raw distance value.<br />
* Indicator LED: fast flash (0.1 s interval) during startup/firmware update, slow flash (1 s interval) in normal operation.<br />
<br />
== Notes and version constraints ==<br />
* The source does not provide explicit command lines or API calls, so the “commands” array is intentionally left empty.<br />
* Specific firmware version details, exact microcontroller compatibility lists, or platform-specific integration notes are missing – verify before deployment.<br />
* Cascaded wiring requires careful power-supply layout to avoid voltage drops along the chain (see the FAQ entry on cascading).<br />
* Strong sunlight or very bright environments may reduce measurement accuracy.<br />
* All values above come from supplier material; confirm them with your own testing before making product decisions.<br />
