2000m Small Laser Measurer 905nm Optical Distance Sensor
Hi, are you looking for a long range optical distance sensor TTL for Drone/ Thermal Sight? This small distance sensor that you need rangefinder sensor for ranges 2 km，with detection probability frequency 1Hz-5Hz. If you can provide more project info of your laser range finder module for 2000m long range, it is very good. Or if you want to know other longer distance sensor infrared, welcome to contact us. Thank you.
If you are planning out your electrical wiring or firmware code blocks, let us know:
Are you connecting this infrared ranging sensor directly to an Arduino/Raspberry Pi (requiring 3.3V TTL logic) or an industrial PLC (requiring an TTL/USB conversion)?
What is your desired sampling speed (Hz)? (e.g., slow static measurements or rapid continuous tracking?)
What is your primary target material to range against?
Range Constraints and Reflectivity Realities
When working with 905nm micro-optical distance sensors, the actual maximum physical range is fundamentally tied to target reflectivity and environmental lighting:
1. High-Reflectivity (Buildings/White Walls): Easily achieves the full 2000-meter baseline of using PTYS-20X2 laser rangefinder sensor.
2. Medium-Reflectivity (Vehicles/NATO targets): Generally limits stable returns to roughly 1000m to 1500m by JRT laser range finder module.
3. Low-Reflectivity (Trees/Natural Terrains/Dark Soil): The reliable distance limits shift downward to around 500m to 800m unless using multi-pulse averaging via this 905nm small laser distance sensor.
