Product overview
The YUSENSE MS400 serves agricultural remote sensing by combining four multispectral channels with a separate RGB channel. Its architecture pairs 1.3 Mpx multispectral imaging with 8.0 Mpx RGB imaging, using global and rolling shutters respectively. Standard spectral channels are 555 nm @ 27 nm, 660 nm @ 22 nm, 720 nm @ 10 nm and 840 nm @ 30 nm, alongside RGB. The manufacturer also lists custom spectral combinations, so procurement should identify the required channel configuration explicitly.
Integration requires space for a main unit published at ≤55 mm × 65 mm × 50 mm and ≤175 g, with an aluminum-alloy body, optical-grade glass window and 7 × M3 mounting interface. Electrical planning should use the specified 12 V supply and ≤7 W consumption at that voltage; other supply voltages require manufacturer consultation. Gigabit Ethernet and TTL serial interfaces support integration, while settings are accessible through Wi-Fi web access, Ethernet or UART. The designated hosts are lightweight small UAVs.
The stated standard configuration includes a downwelling light sensor and a 64G microSD card, with U3 or higher transfer-speed rating required. Capture supports external, timed and overlap-ratio triggers; the published 1 Hz rate depends on actual storage read/write speed. Ground-resolution and coverage figures apply at 120 m height. Operating temperatures of 0 °C to +45 °C require relative airflow ≥1 m/s, and humidity must remain non-condensing. This is a camera payload offering.
