Choose immersion, buoy, flow-cell or pipeline installation for water quality sensors while controlling bubbles, sediment, fouling, pressure and access.

Install and maintain solar radiation sensors with correct level, field of view, cleaning, signal checks, data scaling and reference verification.

Install ultrasonic wind sensors with correct orientation, mast clearance, grounding and heading compensation for fixed stations, vehicles and vessels.

The measurement area of the soil sensor is right around the probe. Mounting quality tends to be more important than “how deep”: as long as there are voids, stones, or loose.

A separate RS485 or analog sensor is usually only responsible for "measuring and outputting", truly sending data to the Internet, requiring a data

One advantage of RS485 is that multiple sensors can share the same A/B bus, but "can be connected in parallel" does not mean "casually

Connecting an RS485 sensor to different hosts essentially accomplishes two things: establishing reliable physical communication and reading data according to the Modbus.
