LoRaWAN Temperature & Humidity Sensor
The ZenoSmart LoRaWAN Temperature & Humidity Sensor accurately measures temperatures ranging from -40°C to +85°C and humidity levels from 0–100% RH, transmitting real-time data via the LoRaWAN network to monitoring centers. With its IP67-rated enclosure and ultra-low power consumption, the sensor ensures reliable performance even in harsh environmental conditions. Powered by a 3.6V battery, the device is simple to install and quickly pairs with a LoRaWAN Gateway to begin data collection. By default, data is transmitted every 15 minutes, though this interval can be adjusted as needed through the IoT platform.
Through the ZenoSmart platform, devices can be monitored remotely, and weekly or monthly reports can be generated for performance analysis. Combined with LTE, Wi-Fi, or Helium networks, cost-effective large-scale monitoring systems can be implemented.
This sensor is ideal for greenhouses and humidity-controlled environments, enabling real-time monitoring of temperature and humidity to support healthy plant growth and create efficient, controlled agricultural conditions.
