Description

The WIN-SN-TnH+IAQ-W sensor combines high-precision digital sensing elements for temperature and humidity with a sophisticated algorithm to generate a comprehensive Internal Air Quality (IAQ) index. This index provides a holistic assessment of air conditions, useful for monitoring ventilation effectiveness and occupant comfort. The sensor’s fully calibrated digital output ensures reliable, ready-to-use data.

Engineered for industrial and commercial environments, the module features robust electrical protection including safeguards against reverse polarity, electrostatic discharge (ESD), and electrical fast transients (EFT). Its 750V isolation enhances signal integrity and system safety in electrically noisy settings. The integrated Wi-Fi module enables wireless data transmission, facilitating remote monitoring and control without extensive cabling.

Key Features

  • Multi-Parameter Environmental Monitoring: Simultaneously outputs precise temperature, relative humidity, and a calculated IAQ index for comprehensive air quality assessment.
  • Industrial-Grade Wireless Connectivity: Built-in Wi-Fi supports both Modbus (RTU/TCP) and MQTT protocols, enabling direct integration with PLCs, HMIs, and cloud IoT services like AWS IoT or Node-RED.
  • Wide Operating Voltage & Electrical Protection: Accepts 12-24V DC with integrated reverse polarity, ESD, and EFT protection, plus 750V isolation for reliable operation in harsh electrical environments.
  • Extended Temperature Range Operation: Functions accurately across an ambient range of -40°C to +85°C, suitable for unheated warehouses, outdoor enclosures, and demanding industrial applications.
  • Web-Based Configuration Interface: Simplifies deployment with an intuitive local web page for connecting to Wi-Fi networks and setting communication parameters without proprietary software.
  • Calibrated for Long-Term Stability: Factory-calibrated sensing elements ensure measurement accuracy is maintained over the product's lifespan, reducing maintenance needs.

Applications

  • HVAC System Monitoring & Control: Provides real-time temperature, humidity, and IAQ data for demand-controlled ventilation (DCV) and building management systems (BMS) to optimize energy efficiency and indoor comfort.
  • Industrial Automation & Condition Monitoring: Monitors environmental conditions in manufacturing facilities, cleanrooms, warehouses, and server rooms to protect sensitive equipment and processes.
  • Smart Building & Workplace IAQ Management: Enables continuous air quality assessment in offices, schools, and public spaces to ensure healthy indoor environments and compliance with wellness standards.
  • Agricultural & Greenhouse Environmental Control: Tracks climatic parameters to automate heating, cooling, and humidification systems for optimal plant growth conditions.

Frequently Asked Questions

What communication protocols does the WIN-SN-TnH+IAQ-W sensor support?

The sensor supports Modbus (both RTU and TCP variants) and MQTT protocols, all transmitted over its integrated Wi-Fi connection. This allows direct integration into industrial SCADA systems using Modbus or into cloud-based IoT platforms like AWS, Azure IoT Hub, or local brokers like Mosquitto using MQTT.

What is the power supply requirement for this sensor?

The module requires a 12V to 24V DC power supply and has a maximum operating current of approximately 1 Ampere. It includes built-in protection against reverse polarity connection, ensuring the sensor is not damaged if the power wires are accidentally connected backwards.

How do I configure the Wi-Fi settings on this sensor?

Configuration is performed via a web interface. Connect the sensor to power, then use a computer or smartphone to connect to the sensor's own Wi-Fi access point. Open a browser to access the configuration page where you can input your local network's Wi-Fi credentials and set communication parameters like Modbus slave ID or MQTT broker details.

What does the IAQ (Internal Air Quality) index represent?

The IAQ index is a calculated value on a scale from 0 to 500 that provides a comprehensive assessment of indoor air conditions. It is derived from the sensor's internal algorithms, likely factoring in volatile organic compound (VOC) levels and other environmental parameters, to give a single metric for overall air quality health.
