Air Temperature & Humidity Sensor
The ZenoSmart LoRaWAN Air Temperature & Humidity Sensor precisely measures temperature from -40°C to +85°C and humidity from 0-100% RH and transmits it to the monitoring center over the LoRaWAN network. Its IP67 protected design and low energy consumption ensure reliable performance in harsh environmental conditions.
The ZenoSmart Air Temperature & Humidity Sensor improves plant health and farming efficiency by tracking ambient temperature and humidity in greenhouses, fields and controlled areas. It runs on a 3.6V battery and installs quickly. After installation, the sensor pairs with a LoRaWAN Gateway and starts sending data. The default interval is 15 minutes, but you can adjust it easily through the IoT platform.
With the ZenoSmart online platform, you can check sensor data remotely and review daily, weekly or monthly reports. The sensor tracks ambient conditions in real time and helps you maintain the ideal environment for plant growth. This support leads to healthier plants and higher production.
You can create low-cost monitoring systems over large areas with LTE, Wi-Fi or the Helium network. The sensor offers accurate measurements and smart IoT control features. It helps you save energy, increase yield and reach your sustainability goals. The ZenoSmart Air Temperature & Humidity Sensor stands out as a reliable and easy-to-use solution for modern agriculture.
