Manufacturer warranty Description
Monnit, MNS2-9-W2-HU-RH-L03, Wireless Humidity Sensor AA Battery Powered
MNS2-9-W2-HU-RH-L03 Includes Only:
- Wireless Sensor Mounting Hardware
- 2 x AA Batteries
Features:
- Humidity Measurement Range: 0 to 100%
- Temperature Measurement Range:
- Leaded: -25°C to 70°C (-13°F to 158°F)
- Non-leaded: Limited to the operational range of the sensor body (enclosure and battery)
- Resolution: 0.01% RH, 0.01°C
- Typical Accuracy: ± 2% RH, 0.3°C
- Configurable thresholds for critical condition monitoring
- Wireless range of 2,000+ feet through 18+ walls
- Frequency-Hopping Spread Spectrum (FHSS)
- Best-in-class interference immunity
- Best-in-class power management for longer battery life
- Encrypt-RF Security (Diffie-Hellman Key Exchange + Advanced Encryption Standard (AES)-128 Cipher Block Chaining (CBC) for sensor data messages)
- Sensor logs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through power cycling):
- 10-minute Heartbeats = ~ 22 days
- 2-hour Heartbeats = ~ 266 days
- Automatic over-the-air updates to sensor firmware (future-proof)
Applications:
- Ambient humidity/temperature monitoring
- Lab monitoring
- Indoor/outdoor environmental monitoring
- Greenhouse and grow house monitoring
- Smart machines and facilities
- HVAC operation and testing
- Data center monitoring
The ALTA Wireless Humidity Sensor measures relative humidity (RH) and temperature on a user-configurable time interval or Heartbeat. The sensor uses a high-accuracy silicon based digital humidity/temperature element to produce % RH and temperature data.
