Leaf Temperature Humidity Sensor for Agricultural High Precision Measuring Moisture Transmitter Sensors Module IP68 RS485 4-20mA

The Leaf Temperature Humidity Sensor for Agricultural High Precision Measuring is designed for monitoring leaf-related environmental conditions in agricultural and horticultural applications.

Monitoring environmental conditions around crops can help farmers, researchers, and automation systems collect useful data about plant environments. This sensor is designed to provide measurements related to leaf temperature and leaf moisture or humidity conditions.

Depending on the selected version, the sensor may provide data through RS485 Modbus RTU communication or a 4–20mA industrial analog signal.

Its IP68 protection rating makes it suitable for compatible agricultural and outdoor monitoring environments where protection against environmental exposure is important.

Leaf Temperature Monitoring

Leaf temperature can provide useful information about plant and environmental conditions.

Leaf temperature monitoring can be used in:

• Smart agriculture
• Greenhouse monitoring
• Crop research
• Environmental studies
• Precision farming
• Automated agricultural systems

Temperature measurements can be collected by a compatible controller, data logger, or IoT monitoring platform.

Leaf Moisture and Humidity Monitoring

The sensor is designed to monitor moisture or humidity-related conditions associated with the leaf environment.

Depending on the sensor design, these measurements may be useful for monitoring:

• Leaf wetness conditions
• Crop environmental conditions
• Moisture exposure
• Greenhouse environments
• Irrigation and agricultural systems

Important: Leaf humidity, leaf moisture, leaf wetness, ambient humidity, and relative humidity are not always the same measurement. The exact measurement method and parameter definition should be verified from the documentation supplied with the specific sensor model.

RS485 Modbus RTU Communication

RS485 is widely used in industrial and agricultural monitoring systems.

The RS485 version can communicate with compatible devices such as:

• PLCs
• Industrial controllers
• Agricultural controllers

Using Modbus RTU, a compatible controller can read sensor values through configured communication settings.

Before connecting the sensor, verify:

• RS485 A/B wiring
• Sensor operating voltage
• Baud rate
• Modbus address
• Parity
• Stop bits
• Modbus register addresses

4–20mA Industrial Output
