System Setup - Generic Sensor

The Pearl has been designed to deliver a high level of flexibility for the advanced growers who often have needs for specialized equipment and controls. One of these features is the ability to support up to 128 generic sensors.

To setup your Generic Sensors from Cloud you would do the following:




to setup your generic sensors from the Pearl controller you would do the following:




The main difference between these generic sensors versus the dedicated sensors (e.g. digital temperature and humidity sensors) is that the variety of supported sensors are much wider. Most industry standard supported sensors (Modbus) are automatically supported. You can contact Link4 directly to verify if your desired sensors are supported. If not, you can also make a request to have them added to the qualified sensor list. Below are

Below are the supported sensor types:



















To get to Generic Sensor you would do the following:


There are additional sensor types here that you don’t see in the traditional sensor list. Such sensors like water level, flow, and dissolved oxygen make the Pearl a good option for irrigation controls. Other applications in addition to the traditional horticultural controls include aquaponic, field irrigation, and many more. Another typical application is to monitor a large number of sensing elements. With 128 sensor inputs, one can collect data from 128 moisture sensors and send them to the cloud for analysis to see soil water content in the root system. Alternatively, 128 temperature sensors to analyze the temperature gradient of a greenhouse over time and 3D space. Keep in mind that this is 128 per Pearl unit.
