Cabinet type temperature and humidity transmitter sensor

OLED LCD screen self-luminous night vision

Magnet suction installation

Double RJ45 hand in hand wiring network

RS485 communication interface, Modbus RTU standard communication protocol

Our YDL-TH02 temperature and humidity transmitter is a cost-effective RS485 temperature and humidity transmitter with OLED liquid crystal display (self-illumination, night vision), which can obtain the current temperature and humidity values ​​in real time through RS485 communication.

YDL-TH02 built-in high-precision imported probe, good ventilation design, can ensure that the built-in probe is consistent with the ambient temperature in real time; OLED LCD screen display, self-luminous night vision, real-time indication of current temperature and humidity values; two RJ45 The terminal is convenient for users to realize RS485 hand-in-hand networking; four magnets are built in the bottom, which can be easily adsorbed on metal surfaces such as cabinets.

YDL-TH02 is a cost-effective cabinet temperature and humidity transmitter mainly for cabinet temperature and humidity monitoring. It can also be widely used in computer rooms, workshops, library and file management, laboratories and other places that require temperature and humidity measurement and control.
