Solid industrial grade sensor

Good build quality and accurate readings compared to our handheld calibrator. The only minor issue was the wiring diagram could be clearer, but support helped us out quickly.

Excellent for greenhouse control

Using this to monitor conditions in a small indoor greenhouse. The response time is quick, and it integrates easily with our Arduino controller using the Modbus library.

Perfect for our server room

We installed three of these units in our data center. The RS485 communication works flawlessly with our existing BMS system. The LCD display is bright and easy to read from a distance.

Great value for Modbus integration

Exactly what we needed for monitoring humidity in our pharmaceutical storage area. Setup was straightforward, and the 86mm form factor fit perfectly into our standard wall boxes.

Does the job well

Accurate temperature and humidity readings. The screen is clear. I deducted one star because the mounting screws were not included, but that's a minor inconvenience.

Reliable and stable

Been running this for six months now without any drift. The data logging via RS485 is consistent. Highly recommend for any industrial monitoring application.

5 FAQ

Q: Can this be powered by PoE?

A: No, this device requires a separate 12V DC or 24V DC power supply. It does not have built-in Power over Ethernet capability.

Q: Does this sensor support Modbus TCP directly?

A: No, this model supports Modbus RTU over RS485. To connect to a TCP network, you will need an RS485 to Ethernet converter gateway.

Q: What is the default baud rate for communication?

A: The default baud rate is 9600 bps, but it can be configured to 2400, 4800, 19200, 38400, or 115200 bps using our configuration software.

Q: How do I calibrate the sensor if readings seem off?

A: The unit comes factory calibrated. If adjustment is needed, please contact our support team for the calibration tool and instructions, as improper calibration may void the warranty.

Q: Is the LCD backlight always on?

A: The backlight is always on by default to ensure visibility in dark server rooms. However, some firmware versions allow setting a timeout to save energy.
