MNS2-9-W2-HU-RH Alta Long Range Wireless IIot Humidity Sensors

Supported Applications

The Omega Alta Long Range Wireless IIoT Humidity Sensors monitor relative humidity (RH), temperature, and dew point within rooms or enclosures. The series is suitable for greenhouse monitoring, agriculture, art galleries, museums, humidors, and general weather/environmental applications.

Operating Conditions & Performance

The sensors measure RH from 0 – 100% with an accuracy of ± 3% under normal conditions (10% - 90% RH). The response time is documented as 8 sec (tau 63%). Wireless range extends to 1,000+ ft. non-line-of-sight using Frequency Hopping Spread Spectrum (FHSS) for interference immunity.

Operating temperature ranges vary by power configuration:

• -7°C to +55°C (20°F to +131°F) for board circuitry and coin cell
• -18°C to 50°C (0°F to 122°F) using alkaline batteries
• -40°C to 80°C (-40°F to 176°F) using lithium batteries or industrial configurations

The series includes onboard data memory for up to 512 sensor messages and supports over-the-air updates. Security is provided via Encrypt-RF™ (256-bit key exchange and AES-128 CTR).

Configuration Options

The Alta Humidity series offers multiple power configurations, including coin cell, AA battery options with 10+ years of life, line power with backup batteries, and an optional solar feature. Enclosure ratings include NEMA 1, 2, 4, 4x, 12 and 13 rated, sealed and weather proof versions.

Key configurable attributes across the series:

• Power Supply: Coin cell; AA batteries (alkaline or lithium); Line power option with barrel connector and backup AA batteries; Optional solar feature with 5VDC/30mA panel and 600 mAh rechargeable battery.
• Data Management: Integrated memory for up to 512 readings; connectivity to the iMonnit Online Sensor Monitoring and Notification System for data review, export as a data sheet or graph, and alert notifications via SMS and email when thresholds are met.
• Certifications: FCC ID: ZTL-G2SC1 (900 MHz), IC: 9794A-G2SC1; CE; Industry Canada compliance with EN 300 220-2 V3.1.1 and EN 60950 for 868/433 MHz products; UL Listed to UL508-4x specifications (File E194432) on industrial models.

Dimensions vary by model: Commercial Coin Cell units measure 2.0 in x 1.125 in x 0.875 in; AA battery versions are approximately 4.375 in x 2.470 in x 1.111 in or 3.701 in x 2.316 in x 1.378 in depending on configuration.

Key Product Differences
