Product Usage Instructions
Installation
Aim the sensor’s adjustable arm at the plant leaves, maintaining a distance of around 20 cm (approximately 8 inches) between the sensor arm tip and the plant leaves.
Data Analysis
Combine temperature data from the sensor with relative humidity measurements to determine dew point and vapor pressure deficit. Use this information to make data-based decisions for plant care.
Creating Virtual Sensors
In the Aranet Cloud platform, create virtual sensors like VPD or dew point using the NEW VIRTUAL SENSOR feature in the Virtual Sensor sheet. Select the appropriate template and choose sensor measurements to create the virtual sensor.
Introduction
The Aranet IR Plant Temperature sensor is designed to measure the surface temperature of plant leaves. An adjustable arm provides precise sensor installation for plant temperature measurements in greenhouse applications making it a valuable tool to calculate Vapor Pressure Deficit (VPD).
Usage
- The sensor uses an infrared (IR) thermometer and adjustable arm for contactless plant leave temperature measurements. The sensor mount has two magnets for simple installation on metallic constructions.
- The sensor provides temperature data, which in combination with relative humidity measurements can be used to determine dew point and vapor pressure deficit.
Use cases
This sensor is crucial for precise vapor pressure deficit (VPD) calculations.
In the Aranet Cloud platform, users can determine VPD by combining plant leaf
temperature data with relative humidity measurements from the T/RH sensor.
VPD parameter informs about the impact of humidity on plant growth. VPD
measures the difference between the moisture in the air and how much moisture
the air can hold at a given temperature.
When the VPD level is high, meaning air is relatively dry, the plant
experiences increased pressure. This increases the transpiration rate and
plants consume more water. Inadequate watering in such conditions can lead to
the wilting of plants. On the other hand, if the VPD level is low, the plant
will transpire less. In such conditions, it is important not to overwater the
plant.
Aim the sensor’s adjustable arm at the plant leaves. Keep in mind that plant
leaves move during the daytime, so maintain a distance of around 20 cm
(approximately 8 inches) between the sensor arm tip and the plant leaves.
To create virtual sensors like VPD or dew point in the Aranet Cloud “Sensors”
section, opt for the “NEW VIRTUAL SENSOR” feature in the Virtual Sensor sheet.
Select the Vapor Pressure Deficit or Dew Point template and choose sensor
measurements to create the appropriate virtual sensor.
FAQ
Q: How does Vapor Pressure Deficit (VPD) affect plant growth?
A: VPD informs about the impact of humidity on plant growth. High VPD levels result in increased pressure, leading to higher transpiration rates and water consumption by plants. Low VPD levels indicate reduced transpiration, necessitating careful watering to prevent overwatering.
Q: What are the benefits of using the Aranet IR Plant Temperature sensor?
A: The sensor provides accurate contactless plant temperature measurements, crucial for calculating VPD. It offers easy installation, wireless operation, and long battery life, making it a valuable tool for greenhouse applications.
