Features of STA0304 Laser Rangefinder module
Safe and harmless to eyes
●Using 1535nm pump Q-switched erbium glass laser, safe for eyes.
●High reliability and long service life.
Easy to operate and secondary development
●Full duplex RS422 electrical interface, equipped with instruction set and communication protocol, convenient user secondary development.
Exchange optimization
●With its very small and ultra-light design and optimized power consumption, the STA0304 is ideal for a variety of handheld devices, weapon mounting applications, portable thermal imaging systems and lightweight sensor suites for use in UAVs or UGVs.
Large measuring range and high precision
●Maximum measuring range ≥ 4km (wall)
●Measurement range of 2.3m × 2.3m vehicles ≥ 3km
●Ranging accuracy ±1m. High precision, more accurate distance measurement results.
●Weight ≤ 35g. Light weight and small size.
