LMS01-LS LoRaWAN Leaf Moisture Sensor 868MHz with Solar

The LMS01-LS LoRaWAN Leaf Moisture Sensor is an advanced IoT device specifically designed for monitoring leaf moisture and temperature in agriculture. Thanks to its robust construction, the sensor is ideal for outdoor use. It utilizes 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 outdoors. Each sensor is 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 when powered on, provided network coverage is available.

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, aiding in 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 power consumption.
