Environmental monitoring as the basis for demand-oriented irrigation
It has always been important to use water responsibly, and this is especially true in times of climate change. Comprehensive environmental monitoring is the first step towards making extreme events such as flooding or drought more manageable. In urban environments, for example, soil moisture is measured in green spaces. This is how demand-oriented irrigation is realized.
The new PMD EM wireless soil moisture sensor from Phoenix Contact is part of a comprehensive LoRaWAN® network and can be individually adapted to any type of soil through simple parameterization. This adaptation ensures that the soil moisture values are interpreted correctly. Whether the soil is clayey or sandy, the amount of moisture available varies depending on the soil type and the recorded water content must be interpreted correctly. The 30 cm long sensor provides the volumetric water content of the soil as a percentage. Up to six measured values can be stored in the sensor and made available to the LoRaWAN server every hour. The sensor also records the temperature close to the ground.
The soil moisture sensor features IP67 degree of protection, is 100 percent maintenance-free, and has a service life of up to eight years, depending on the transmission interval and location.
To decode the payload sent from the sensor to the LoRaWAN server, a JavaScript library is available for integration into your own application.
In addition to use in parks and green spaces, applications on sports fields, in greenhouses, on plantations, and agricultural land are also conceivable.
