• Temperature: -20 °C to +50 °C, ±0.2 °C accuracy
• Humidity: 0 to 100 %RH, ±2 %RH accuracy
• Barometric pressure: 300 to 1100 hPa, ±1 hPa accuracy
• LoRaWAN Class A, supports EU868, US915, AS923, AU915, KR920, IN865
• Powered by one 3.6V AA lithium battery, up to 10 years life
• NFC configuration interface for simple setup
• IP40 enclosure, wall or surface mount
• Certifications: CE, FCC, IC, RCM, LoRaWAN Certified

Why choose it

This sensor eliminates the need for frequent battery replacements and manual readings. Its long-range LoRaWAN connectivity ensures data reaches your network even in challenging environments, while the integrated environmental sensors provide a complete picture of the monitored area. AES128 encryption keeps your data secure.

Ideal use cases

• Monitoring fill levels of tanks, silos, and waste containers
• Parking space occupancy detection in garages or lots
• Object proximity or presence detection in industrial automation
• Environmental monitoring in warehouses, greenhouses, or cold chains

Good to know

The reporting interval is configurable from 5 minutes to 24 hours, allowing you to balance data granularity and battery life. Setup is quick via NFC using a smartphone app, and the sensor is compatible with any LoRaWAN network server. For outdoor use, consider an additional protective enclosure as the IP40 rating is intended for indoor or sheltered locations.
