Leaf Moisture Sensor
ZenoSmart LoRaWAN Leaf Moisture Sensor precisely measures moisture and temperature values on the leaf surface of plants, providing data for irrigation, dew, humidification and frost risk analysis. Thanks to LoRaWAN connectivity, this data is instantly transmitted to cloud platforms, making agricultural decision processes more informed.
The ZenoSmart Leaf Moisture Sensor offers reliable performance in the open field for long periods of time thanks to its IP67 protected construction and special design in leaf form. The device is battery powered and extremely easy to install; data collection starts automatically when the probe is placed in the appropriate area.
By default, the sensor sends data every 15 minutes and this interval can be easily adjusted according to user needs via the IoT interface. Through the ZenoSmart platform, data can be tracked and analyzed in daily, weekly or monthly reports.
The Leaf Moisture Sensor accurately determines the actual water requirement of plants, preventing over-irrigation and yield losses. It also supports the healthy development of plants by reducing the risk of diseases and pests. Thus, agricultural yield is maximized and sustainable agricultural practices are strengthened.
