Easy installation and setup
The wiring diagram provided in the manual was very clear. I had it mounted and communicating over Modbus within 20 minutes. The enclosure feels robust and suitable for harsh environments.

Excellent value for money
I've used much more expensive brands in the past, and this Lefoo unit performs just as well for a fraction of the cost. The humidity response time is quick, which is critical for our pharmaceutical storage area.

Solid industrial sensor
Great build quality and accurate readings compared to our calibrated reference meter. The only minor issue is that the menu navigation takes a little getting used to, but once configured, it works flawlessly.

Reliable data logging source
Been running these for three months now without any drift or connectivity issues. The dual output option (analog and digital) gives us great flexibility for redundancy in our control system.

Highly recommended for automation
This transmitter integrates perfectly with our SCADA system. The accuracy specs are spot on, and the customer support team was helpful when I had questions about the baud rate settings.

Perfect for our HVAC monitoring system
We installed six of these units in our warehouse to monitor climate control zones. The RS485 integration was seamless with our existing PLC, and the 4-20mA output is very stable. The display is clear and easy to read from a distance.
Q: Can this be used outdoors in direct rain?
A: While it has an IP65 rating which protects against water jets, we recommend installing it under an eave or shelter for prolonged outdoor use to ensure maximum longevity.
Q: What is the length of the cable included with the wall mount?
A: This unit does not come with a pre-attached cable; it has terminal blocks inside the junction box for you to wire your own cables according to your installation needs.
Q: Can this device operate on 12V DC power?
A: No, the LFH10A requires a power supply between 15V and 30V AC/DC. We recommend using a stable 24V source for optimal performance.
Q: How do I calibrate the humidity reading if it seems off?
A: The device features a user-calibration function in the settings menu. Please refer to page 12 of the user manual for step-by-step instructions on offset adjustment.
Q: Is the RS485 communication protocol Modbus RTU compatible?
A: Yes, this sensor uses the standard Modbus RTU protocol over RS485. You can configure the slave ID and baud rate directly via the device buttons.
