Product overview
The ERDI Laser LR1000D25 brings laser distance measurement to OEM observation and surveying equipment through a UART-TTL interface. Its 905 nm ± 5 nm laser operates at a measurement frequency of 3–10 Hz. The module weighs approximately 23 g and measures Ø25 × 46.1 mm. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu. Electrical requirements are a 3.3–5 V supply, with ≥3.5 V recommended within that range, and average operating power below 0.8 W.
The measurement range is 4–1,000 m under manual test conditions using 90% reflective targets measuring 2.3 × 2.3 m and 2.3 × 4.6 m, with a white-board accuracy reference. Ranging accuracy is ±1 m at distances of 6 m ≤ d less than 400 m with a 2.3 × 2.3 m target, 90% reflectivity and a white-board reference. The module supports storage temperatures from −40 to +60 °C.
