Enabling better global research outcomes in soil, plant & environmental monitoring.

Decagon ES-2 Sensor

The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank. When you pair the new ES-2 with a GS3 or 5TE in the soil, you’ll begin to develop a complete picture of the salts that are going into your system as well as the salts remaining in your soil or substrate.

  • Continuous EC measurements in a pipe or tank
  • Direct measurements of pore water EC when used in conjunction with the Wetting Front Fullstop
  • Check your EC values anywhere with an internet connection


Utilising the ES-2 Sensor in a custom IoT (Internet of Things)

The SNiP-ES2 is a ‘Sensor Node Integrated Package’ for LoRaWAN or CAT-M1 communication of real-time electrical conductivity and temperature measurements for continuous water quality monitoring.

The base SNiP-ES2 integrates 1x ES-2 Sensor with 1x S-NODE to a site’s unique network, communication and power requirements. The S-NODE can support an added 3x compatible sensors.
