LMS01-LS LoRaWAN Leaf Moisture Sensor 868MHz with Solar

The LMS01-LS LoRaWAN Leaf Moisture Sensor is a highly advanced IoT device specially developed for monitoring leaf moisture and temperature in agriculture. Thanks to its robust construction, the sensor is ideal for outdoor use. It uses the FDR method to measure the dielectric constant caused by liquid on the leaf surface and converts this value into leaf moisture. This model uses a combination of solar cells and a supporting battery to ensure optimal performance and durability under open skies. Each sensor comes pre-installed with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically connects upon powering on, provided there is network coverage.

Recommended Accessories:

• Lora Gateway

Features:

• Leaf Moisture Measurement: The LMS01-LS accurately measures leaf moisture by capturing the dielectric constant caused by liquid on the leaf surface.
• Temperature Monitoring: It monitors and transmits the temperature of the leaves, contributing to the analysis of leaf status such as irrigation, humidification, dew, and frost.
• Solar Powered: The sensor is powered by a solar panel and a 3000mAh Li-Ion battery, ensuring environmentally friendly and low-maintenance usage.
• LoRaWAN Technology: The sensor utilizes LoRaWAN technology for ultra-long-range communication capabilities with low energy consumption.
• Bluetooth Support: The sensor supports BLE configuration and wireless OTA updates, simplifying setup and maintenance.
• Accuracy: The sensor has high accuracy with a resolution of 0.1% for moisture and 0.1°C for temperature measurements.

Application Examples:

• Smart Irrigation: Optimization of irrigation schedules based on real-time leaf moisture data.
• Frost Monitoring: Early warning system for frost danger by monitoring the temperature of the leaves.
• Plant Protection: Monitoring of moisture to prevent plant diseases that are promoted by excessive moisture.
• Climate Research: Collecting microclimate data to support research projects.
• Agricultural Research: Analysis and improvement of cultivation methods through accurate data.
