The Challenge

This research project conducted by Newcastle University investigated the interrelationship between soil health and potato crops by gaining a better understanding of soil properties at root level with particular focus on the effects of O2 and CO2 on plant health.

A remote monitoring system was required to measure soil oxygen, carbon dioxide, acidity, moisture and temperature in addition to ambient lightng levels.

The system had to operate autonomously over the period of a complete growing season, logging and tranmitting data once per hour.

The Solution 

Based on a mixrure of of our green infrastructure monitoring hardware and our EDEN technology platform we developed a fully autonomous solar-powered soil monitoring station for the real-time in-situ in-field measurement of soil parameters including soil moisture, soil temperature, electrical conductivity, pH, CO2, Oxygen, as well as light levels incident on the crop.

The station transmitted monitoring data as well as system health information such as battery charge status and wireless signal level in real time via GSM to our cloud-based platform where to has accessed and interrogated via a secured user account.
