Maintaining the right environment is crucial when preserving sensitive materials, whether they are priceless artifacts, critical data, or delicate inventory. One key factor often overlooked is humidity. Keeping relative humidity (RH) between 40 and 60 per cent can prevent damage caused by moisture or dryness. Wireless humidity and temperature sensors provide a reliable way to monitor these conditions remotely and respond quickly to changes.
Why Humidity Control Matters in Preservation
Humidity affects materials in many ways. Too much moisture can cause mould growth, corrosion, and warping. Too little can lead to cracking, brittleness, and static buildup. For example, wooden artifacts may swell or shrink, paper documents can become brittle, and electronic equipment may malfunction due to condensation or dryness.
Maintaining RH between 40 and 60 per cent creates a stable environment that slows deterioration and extends the life of sensitive items. This range is widely accepted by museums, data centres, and food storage facilities as optimal for preservation.
How Wireless Sensors Improve Monitoring
Traditional humidity monitoring often requires manual checks or wired sensors that limit placement options. Wireless humidity and temperature sensors offer several advantages:
Remote access: Monitor conditions from anywhere using smartphones or computers.
Real-time alerts: Receive instant notifications via text, email, or calls if humidity or temperature goes outside set limits.
Flexible installation: Place sensors in hard-to-reach or multiple locations without running cables.
Accurate readings: Scientific-grade sensors provide precise measurements with +/- 3% accuracy in the 10–90% RH range.
These features allow facility managers to act quickly before damage occurs, reducing risk and saving costs.
Sensor Options for Different Needs
Monnit ALTA® Wireless and Next™ Wi-Fi Humidity Sensors come in various models to suit different environments:
Commercial and enterprise wireless sensors for offices, galleries, and museums.
Industrial wireless sensors are designed for harsher conditions in manufacturing or agriculture.
Wi-Fi and Power over Ethernet (PoE) sensors for facilities with existing network infrastructure.
Customisation options include lead lengths from 3 to 25 feet, NIST certification for calibration, and solar power for remote locations. This variety ensures the right sensor fits each unique preservation challenge.
Real-World Applications
Many organisations rely on wireless humidity and temperature sensors to protect valuable assets:
Museums and art galleries use sensors to maintain stable conditions around paintings, sculptures, and historical artifacts.
Data centres monitor humidity to prevent static discharge and condensation that could damage servers.
Food processors and agriculture track storage environments to ensure product quality and safety.
Life sciences laboratories maintain precise conditions for samples and experiments.
For example, an Ivy League museum installed Monnit ALTA® sensors throughout its exhibit halls and storage rooms. When a sensor detected rising humidity near a rare manuscript, staff received an alert and adjusted the HVAC system immediately. This quick response prevented mold growth and preserved the manuscript’s integrity.
Best Practices for Using Wireless Sensors
To get the most from wireless humidity and temperature sensors, consider these tips:
Place sensors strategically near sensitive items, HVAC vents, or areas prone to moisture buildup.
Set clear alert thresholds based on the specific needs of your materials.
Regularly calibrate sensors to maintain accuracy, especially for scientific or regulatory compliance.
Integrate sensor data with facility management systems for centralized monitoring.
By following these steps, organizations can build a strong defense against environmental damage.
Summary
Wireless humidity and temperature sensors play a vital role in preservation management by providing accurate, real-time monitoring of critical environmental conditions. Their flexibility, precision, and alert capabilities help protect valuable assets from irreversible damage caused by improper humidity levels. Selecting the right sensor model and using it effectively ensures that artifacts, data, and inventory remain safe for years to come.
