Description
LCD temperature humidity sensor description:
The wall-mounted temperature humidity sensor with display adopts standard MODBUS-RTU communication protocol, RS485 signal output, and the maximum communication distance can reach 2000 meters. The built-in probe is used by default, and the extension probe can also be used if necessary.
LCD display temperature humidity sensor features:
1. The housing of the temperature-humidity sensor is made of white ABS waterproof plastic material, equipped with a full-screen large LCD, and the installation is beautiful and generous.
2. The temperature humidity sensor uses a high-precision temperature and humidity measurement unit, which can be self-calibrated on site, and has good long-term stability.
3. 10~30V DC wide voltage range power supply
4. The built-in extension of the probe is optional. The built-in type of probe is easy and convenient to install. The extension type of the probe can be used in different applications. The probe cable can be up to 30 meters long.
5. The temperature and humidity device itself has buttons to set parameters, which is easy to operate.

Application
This LCD temperature humidity device is widely used in warehouses, pharmaceutical factories, computer rooms, industrial workshops, offices, and other environments that require temperature and humidity monitoring.
FAQ
Q: Why the temperature-humidity device cannot connect to the PLC or computer:
A: 1. The computer has multiple COM ports and the selected port is incorrect.
2. The address of the temperature and humidity device is wrong, or there are devices with duplicate addresses (the factory defaults are all 1).
3. The baud rate, check method, data bit and stop bit are wrong.
4. The host polling interval and waiting response time are too short, and both need to be set above 200ms.
5. The 485 bus is disconnected, or the A and B wires are connected reversely.
6. If the number of temperature and humidity equipment is too large or the wiring is too long, power should be supplied nearby, and a 485 intensifier should be added and a 120Ω terminal resistance should be added.
7. The USB to 485 drivers is not installed or damaged
8. The temperature and humidity equipment is damaged.
