Product Overview

(Integrated Alarm Light: Green – Normal / Red – Warning)

Monitoring temperature and humidity is critical in many industrial and storage environments. To ensure optimal conditions, reliable and continuous measurement is essential. The AT-THMT-T Industrial Temperature and Humidity Sensor is a professional solution designed to provide real-time, easy-to-read environmental data indoors, while featuring an integrated two-color Alarm Light (Green/Red) for instant visual alerts.

This device is ideal for applications such as warehouses, factories, cold storage, offices, and any indoor space that requires constant monitoring of temperature and humidity.

Applications in Data Centers

The AT-THMT-T Industrial Temperature & Humidity Monitoring Display Board is installed in a data center server room corridor. The large, high-brightness LED display provides clear visibility of real-time temperature and humidity values from long distances. The intelligent dual-color background indicator allows maintenance personnel to instantly assess environmental conditions. A green background indicates normal operating conditions, while a red background signals that temperature or humidity thresholds have been exceeded.

The Problem

Environmental conditions play a critical role in the performance of industrial equipment, data centers, laboratories, pharmaceutical storage facilities, and manufacturing processes.

Most conventional temperature and humidity meters use small displays that can only be viewed from close distances. Facility personnel must physically approach each device to verify environmental conditions, increasing inspection time and reducing operational efficiency.

More importantly, temperature spikes or humidity fluctuations may go unnoticed until equipment failures, product damage, process deviations, or costly downtime occur. Software alarms alone are often insufficient because alerts are only visible when operators are actively monitoring a computer screen.

Organizations require a highly visible environmental monitoring solution that provides instant status recognition and immediate alarm notification.

The Solution – AT-THMT-T

AT-THMT-T is an industrial temperature and humidity display board designed to provide real-time environmental monitoring with maximum visibility and immediate alarm indication.

The system combines high-precision Swiss sensor technology, industrial-grade electronics, and a patented dual-color visual alert system to deliver reliable monitoring performance in critical environments.

System Features

Large LED Display

Large 7-segment LED digits measuring 5cm × 7cm provide clear visibility from distances exceeding 20 meters.

High-Precision Swiss Sensor

Equipped with the Sensirion SHT30 sensor for accurate temperature and humidity measurement.

Measurement Range:

• Temperature: -40°C to +125°C
• Humidity: 0% to 100% RH

Industrial-Grade Controller

Powered by the Microchip PIC16F887 industrial microcontroller for stable 24/7 operation.

Dual-Color Background Alarm System

The entire display background automatically changes color according to environmental conditions.

Green Background:

• Temperature within configured limits
• Humidity within configured limits

Red Background:

• Temperature exceeds configured threshold
• Humidity exceeds configured threshold

Industrial Construction

Designed with a durable aluminum profile frame and a 3mm protective Taiwanese Mica front cover suitable for industrial applications.

Key Features of AT-THMT-T (With Green/Red Alarm Light)

The AT-THMT-T is designed to provide stable and accurate temperature and humidity monitoring in indoor industrial environments. With a clear LED display, wide measuring range, optional Modbus communication, and especially an intelligent two-color Alarm Light, this device supports proactive supervision and instant alerting when parameters exceed allowable thresholds.

LED Display with Multiple Visibility Options

The AT-THMT-T displays temperature and humidity values on a red LED display. Other LED color options (amber, blue, green) may be available as default variants.

Large Format for Indoor Monitoring

With a screen size of 350mm × 600mm × 50mm, this display is suitable for indoor industrial environments where visibility is important.

Wide Measurement Range

The unit supports a broad measuring range for different environmental setups:

• Temperature: -40°C to +125°C
• Humidity: 0% to 100% RH
  Combined with a working environment range of -20°C to 60°C and 0–95% RH, the device adapts to most indoor industrial conditions.

Accurate and Clear Readings

The instrument provides:

• Resolution: 0.1°C, 0.1% RH
• Accuracy: ±1°C, ±5% RH
  Reliable readings help reduce the risk of environmental issues that might affect product quality or processes.

INTEGRATED ALARM LIGHT – GREEN / RED (Key New Feature)

To enhance proactive monitoring, the AT-THMT-T is equipped with a high-intensity two-color Alarm Light on the front panel:

• Operating mechanism: Users can set minimum/maximum thresholds for temperature and humidity via push buttons or software or industrial keypads. When measured values are within range → Green light. When either parameter exceeds the threshold → immediately switches to Red light.
• Benefit: Operators can visually monitor from a distance just by looking at the light color, without needing to read the exact numbers. Response time is reduced to just seconds.
• Real-world applications: Extremely useful in cold storage, server rooms, pharmaceutical factories, food warehouses, chemical storage – where any delay in detecting anomalies can cause significant losses.

Modbus RTU RS485 Communication (Optional)

This display can be integrated with automation systems such as PLC or SCADA via Modbus RTU RS485, allowing centralized monitoring and data collection. The alarm light status (Green/Red) can also be transmitted to the control center.

Indoor Use and Protection Rating

Designed for indoor environments (e.g., warehouses, factories, offices), the AT-THMT-T supports a protection rating of IP50 to resist dust and ensure durability in industrial settings.
