DRAGINO NB-IoT Leaf Moisture and Temperature Sensor
DRAGINO NB-IoT Leaf Moisture and Temperature Sensor is an NB-IoT leaf moisture sensor designed for agricultural monitoring applications. It measures leaf moisture and leaf temperature and transmits the collected data to an IoT platform for monitoring and analysis. The leaf-shaped probe uses FDR technology to detect moisture on the leaf surface, while NB-IoT connectivity enables remote data transmission. The sensor also supports Bluetooth v5.1 configuration, OTA firmware updates and an 8500mAh Li-SOCI2 battery for long-term operation.
The DRAGINO NB-IoT Leaf Moisture and Temperature Sensor monitors leaf moisture and leaf temperature for smart agriculture applications. Its leaf-shaped IP67-rated probe is designed to simulate the characteristics of a real leaf and detect moisture across the leaf surface. Data can be transmitted through NB-IoT using supported protocols including MQTT, MQTTs, UDP and TCP.
Full product description
The DRAGINO NB-IoT Leaf Moisture and Temperature Sensor is designed for remote leaf condition monitoring in agricultural IoT systems. It measures both the amount of moisture present on the leaf surface and leaf temperature, allowing collected data to be sent to an IoT platform for analysis.
The sensor uses FDR (Frequency Domain Reflectometry) to detect changes in the dielectric constant caused by liquid on the leaf surface. Its probe has a leaf-shaped design intended to reproduce the characteristics of a real leaf, with a stated density of 15 leaf vein lines per centimetre to help detect small moisture droplets.
How it works
- The leaf-shaped probe is positioned to monitor moisture on the leaf surface.
- FDR technology detects changes caused by liquid on the surface of the probe.
- The sensor converts the detected moisture condition into a leaf moisture reading from 0 to 100%.
- Leaf temperature is measured alongside moisture.
- Measurements can be sampled multiple times before being transmitted in an uplink.
- The collected data can be sent over NB-IoT using supported communication protocols such as MQTT, MQTTs, UDP and TCP.
Why choose this product?
- Direct leaf condition monitoring - Measures leaf moisture and temperature rather than relying only on general environmental measurements.
- NB-IoT connectivity - Designed for wireless transmission of sensor data to compatible IoT platforms.
- Designed for outdoor sensing - The sensor probe has an IP67 protection rating, while the enclosure is rated IP66.
- Remote configuration - Bluetooth v5.1 can be used for remote configuration and firmware updates.
- Long-term battery operation - Uses an 8500/19000mAh Li-SOCI2 battery, Solar panel + 3000mAh Li-ion battery or 1000 mAh rechargeable Li-ion battery specified for long-term operation.
- Flexible data integration - Supports several uplink protocols and can connect with different IoT server environments.
Benefits
The DRAGINO NB-IoT Leaf Moisture and Temperature Sensor can provide more detailed information about leaf surface conditions than temperature monitoring alone. Its remote connectivity allows measurements to be collected without requiring a wired data connection to the sensor, making it suitable for distributed agricultural monitoring installations.
