The ClimateMinder Wireless Network is a patent-pending technology system enabling field sensors and controls to work together seamlessly. It includes a self-adjusting wireless network of nodes (with sensors or controls that can be attached to each node) and a gateway that communicates with the ClimateMinder Web Server. ClimateMinder Wireless Network provides the flexibility growers need.
Each network node is able to communicate wirelessly with other nodes. There are sensor nodes for monitoring important conditions like temperature, humidity, soil moisture, solar radiation and leaf wetness, and relay controls for activating devices like irrigation, heating, vents, lighting, misting and fans. Each node is capable of operating up to four sensor probes or up to eight relays. Click below for more information
The ClimateMinder wireless network is a collection of nodes, each of which is able to communicate with the other nodes using a radio module. One or more sensors or control relays are connected to each node. Each node controls whatever sensors or relays are attached to it, communicating sensor or control data to and from the Gateway mode. The Gateway node is the node that communicates with the ClimateMinder Server using a GSM modem.
Each node is a weather-proofed enclosure containing the hardware components required for its task, possibly including: wireless radio, external antenna, battery, interface module, power module, GSM radio, and node controller.
Nodes form a self-configuring network (when the device is switched on, it introduces itself to the network and finds its neighboors to send data), that is also self-healing (if a node is broken along the route, other nodes route information through another path), and is optimized for low power operation.
There are 3 kinds of nodes:
Sensor or control node |
8-way controller |
Gateway node |
Technical Specifications for each node:
Sensors are measurement devices that are connected to wireless nodes. The environmental values that can be measured by the ClimateMinder sensor nodes are: Ambient temperature and humidity, Soil Moisture, Soil Moisture/Temperature/Electrical Conductivity (EC), Solar Radiation and Leaf wetness.
The CM-SP-TH digital humidity and temperature sensor is a high-quality humidity sensor series with cutting edge accuracy. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. The capacitive humidity sensor is fully calibrated and provides a digital output. Every humidity sensor is tested upon quality and accuracy compliance. Certficate of conformance on batch level is available on request.
The CM-SP-SMS sensor for measuring soil water content will enable you to monitor soil moisture accurately and affordably
This probe measures the dielectric constant of the soil in order to find its volumetric water content. Since the dielectric constant of water is much higher than that of air or soil minerals, the dielectric constant of the soil is a sensitive measure of water content.
The two-prong design and higher measurement frequency allows the sensor to measure VWC from 0 to 100%, and allows accurate measurement of all soil types and a much wider range of salinities.
Sensor technical specifications:
The CM-SP-SMEC is designed to measure the water content, electrical conductivity, and temperature of soil and growing media. Using an oscillator running at 70 MHz, it measures the dielectric permittivity of soil to determine the water content. A thermistor in thermal contact with the probe prongs provides the soil temperature, while the screws on the surface of the sensor form a two-probe electrical array to measure electrical conductivity.
The CM-SP-SR Pyranometer Sensor, or solar radiation sensor, is calibrated to measure the shortwave radiation reaching the Earth's surface, measured in Joules m-2 s-1 or Watts m-2. The evaporation of water from soil and the transpiration of water from plant leaves are partly determined by the intensity of shortwave radiation
Sensor technical specifications:
The CM-SP-LWS Leaf Wetness Sensor (LWS) determines the presence and duration of canopy wetness, allowing you to forecast disease and protect the plant canopy. Because the Leaf Wetness Sensor measures the dielectric constant, droplets do not need to bridge electrical traces for the sensor to detect moisture. The presence of water or ice anywhere on the surface of the sensor will be detected. The sensor measures leaf surface wetness by measuring the dielectric constant of the sensor’s upper surface.
