Wireless Humidity & Temperature Sensor – High-Accuracy RH Monitoring

The ALTA® Wireless Humidity Sensor is a high-performance solution for monitoring relative humidity (RH) and ambient temperature in real-time. Built with a factory-calibrated industrial-grade transducer, it delivers dependable accuracy for use in commercial, industrial, and controlled-environment applications.

Available in leaded and non-leaded configurations, the sensor offers flexibility for different installation needs. Leaded versions provide extended temperature range monitoring, while non-leaded models offer compact, enclosed setups.

With high-resolution readings (0.01% RH / 0.01°C) and typical accuracy of ±2% RH and ±0.3°C, this sensor is ideal for environmental tracking, HVAC systems, food storage, cleanrooms, and more. Configurable thresholds allow users to receive alerts when humidity or temperature levels fall outside desired ranges.

⚠️ Note: Requires a compatible Monnit gateway and may require software. See our Gateway & Software section or browse pre-configured kits.
