About - temperature humidity display board
Our this big temperature humidity display panel has two sensor type is Internal or external sensor (different models). If you want to install outside a cold storage room, the display has to be mounted outside the cold room and the external sensor has to be inserted into the cold room. The display is visible from a distance of up to 50 meters. This temperature humidity display panel is mainly for indoor applications. For more information about the appearance of this product, please check out the video of the temperature and humidity display board on the right.
Features
The RS-WS-*-K1-*-EX temperature and humidity display panel is equipped with a high-precision imported sensor for accurate measurement. It features a high-brightness red LED digital display, ensuring clear readability even at night or under strong ambient light.
The device is built with an integrated buzzer to trigger alarms when readings exceed preset thresholds. Designed for versatile installation, it supports both wall-mounting and hanging methods, making it suitable for various environments such as offices, laboratories, supermarkets, workshops, warehouses, and hospitals.
Multiple output options are available, including RS485, 4–20 mA, 0–5 V, 0–10 V, and Wi-Fi. The RS485 series supports the standard ModBus protocol, with a communication range of up to 2000 meters and is compatible with secondary development. The Wi-Fi series leverages existing wireless network infrastructure for data acquisition and transmission, enabling centralized temperature and humidity monitoring. This significantly reduces installation workload, improves deployment efficiency, and lowers maintenance costs.

- Product certificate, warranty card, and related documentation
- Mounting screws ×1 set
2. What is the calculation method for analog output models?
Current output signal conversion calculation
For example, with a range of -40 to +80℃ and a 4–20 mA output, when the output signal is 12 mA, the current temperature value can be calculated. The span of this temperature range is 120℃, represented by a 16 mA current signal. 120℃ / 16 mA = 7.5℃/mA, meaning that each 1 mA represents a 7.5℃ temperature change.
Measured value: 12 mA – 4 mA = 8 mA.
8 mA × 7.5℃/mA = 60℃.
60 + (–40) = 20℃, so the current temperature is 20℃.
Voltage output signal conversion calculation
For example, with a range of -40 to +80℃ and a 0–10 V output, when the output signal is 5 V, the current temperature value can be calculated. The span of this temperature range is 120℃, represented by a 10 V voltage signal.
120℃ / 10 V = 12℃/V, meaning that each 1 V represents a 12℃ temperature change.
Measured value: 5 V – 0 V = 5 V.
5 V × 12℃/V = 60℃.
60 + (–40) = 20℃, so the current temperature is 20℃.
3. How to wire?
Analog output type: Connect the brown wire to the positive terminal of the temperature signal, the black wire to the negative terminal of the temperature signal, the blue wire to the positive terminal of the humidity signal, and the yellow (green) wire to the negative terminal of the humidity signal.
RS485 output type: Connect the red wire to 485-A, and the black wire to 485-B.
4. What are the advantages of temperature and humidity board?
- Ensure indoor environmental comfort
Temperature humidity display panels help control indoor temperature and humidity, ensuring a comfortable and healthy environment. During summer, if the indoor temperature becomes too high, the panel can trigger an alarm to remind occupants to turn on the air conditioning promptly. In winter, if the indoor temperature is too low, the panel can also issue an alert to prompt timely temperature adjustments. - Prevent microbial growth
In humid environments, harmful microorganisms such as bacteria and mold can easily proliferate, degrading indoor air quality. The display panel monitors indoor humidity levels, assisting users in regulating humidity to control microbial growth effectively. - Improve work efficiency
In offices, factories, and similar settings, fluctuations in temperature and humidity can impact employee productivity. Excessively high or low indoor temperatures cause discomfort, reducing work efficiency. By monitoring the indoor environment with the temperature humidity display panel, appropriate adjustments can be made to optimize temperature and humidity, thereby enhancing employee performance. - Save energy
Air conditioning consumes significant power during summer, and setting the temperature too low not only wastes energy but may also adversely affect employees’ health. Monitoring indoor temperature and humidity with the display panel enables optimized control of air conditioning runtime and settings, conserving energy while maintaining a comfortable indoor environment.
5. How to view data?
This big temperature humidity display panel uses 10~30V power supply, and the shell is made of stainless steel, which is sturdy and durable. It can be installed in offices, supermarkets, laboratories, farms and other places. The measurement data can be read directly through the LCD display, or log in to the free cloud platform provided by our company to view or export historical data.
