Robust and reliable

Installed this on a rooftop HVAC unit three months ago. It has survived rain and high winds without any issues. The readings match our calibrated handheld meter perfectly.

Good precision, easy setup

Works exactly as described. The RS485 wiring is straightforward. I deducted one star because the documentation could be more detailed regarding register maps, but overall a solid unit.

Solid performance

The sensor is accurate and the build quality feels durable. Setup took about 20 minutes including wiring and configuring the baud rate. Very satisfied with the purchase.

Perfect for my weather station project

The MODBUS integration was seamless with my PLC. The thermal sensor responds very quickly to gusts, and the data is consistent. Highly recommended for industrial monitoring.

Great for automation systems

Using this in a greenhouse ventilation control system. The low wind speed detection is sensitive enough to trigger fans appropriately. No drift observed so far.

Excellent value for money

Compared to other industrial sensors, this offers great performance at a fraction of the cost. The thermal type means no moving parts to wear out, which is a huge plus.

5 FAQ

Q: Is calibration required before first use?

A: The sensor comes factory-calibrated. You can start using it immediately after wiring and power-up. Recalibration is typically only needed after several years of operation.

Q: Can this measure wind direction as well?

A: No, this is a single-axis thermal anemometer designed strictly for wind speed measurement. It does not detect wind direction.

Q: What is the maximum cable length recommended for RS485 connection?

A: For reliable communication at standard baud rates (e.g., 9600), you can extend the cable up to 1200 meters using twisted pair shielded cable, provided proper termination resistors are used.

Q: What is the power consumption of this module?

A: The typical power consumption is less than 0.5W at 24V DC, making it suitable for battery-powered or solar-powered remote stations.

Q: Does this sensor support both ASCII and RTU modes?

A: This specific model supports MODBUS RTU mode only. Please ensure your master device is configured for RTU communication.
