Product overview
The ERDILRF LRF22VB is a 905 nm single-point DToF laser rangefinder module for UAV payloads, drone altitude hold, and height measurement during landing and hover. It also serves robot and AGV obstacle sensing and level sensing in small tanks and bins. Its measurement range is 0.05–20 m at 90% target reflectivity and 0.05–10 m at 10% reflectivity. Measurement frequency is 200 Hz, with selectable alternatives of 100, 50, 20, 10 and 1 Hz. Accuracy is ±5 cm below 5 m and 1% at distances of 5 m or greater.
The module measures 21 × 15 × 7.43 mm and weighs 1.5 g, with UART/IIC communication and a 6-pin 0.8 mm HC-0.8-6PWT terminal with 20 cm tinned stranded wires. It requires 3–3.6 V DC, consumes less than 0.2 W on average, and must not be connected to 5 V. Its operating temperature range is −20 °C to +60 °C. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu. Appearance, structure and output protocol can be customized.
