How to guide:

When you register your sensors we send you an email with a link to a complete manual. Here's a few tips for quick reference.


The Green Shield product range is compatible with any data logger or remote telemetry unit with SDI-12 interface.

When bedding the sensor in the soil, it is essential to establish a close bond between soil and sensor surface, avoiding any air gaps.

Drill or dig a hole into the soil, down to the required depth. Sieve the removed soil to remove any stones or debris. Place the sensor at the bottom of the hole and cover it with sieved soil. Pour sufficient water into the hole and wait until it seeps away. Add more soil and water it again. Repeat this procedure until the hole is completely covered.

It is recommended to place the probe in a tilted position rather than in a horizontal or vertical position.


DonĀ“t pull at the cable to remove the soil moisture probe, as it may damage the product and void warrantry. Carefully remove the soil with a small shovel until you can access the body of the sensor. Do not damage the cable jacket or the sensor coating.

An special removal tool can be purchased for easy extraction.

New Parts:

In the case the outer enclosure has too much wear our clients can request new parts at a minimal fee.


As the maximum water storage capacity largely depends on the soil type, the sensors come factory calibrated.
