To install the Stoock, you need to drill a hole in the soil with the same length as the sensor, remove a sample from the soil, mix it with water in a bucket and put it back into the hole. Place the sensor in the hole, guide the solar panel towards South if you’re in the Northern Hemisphere or North if you’re in the Southern Hemisphere. Then, click the button on top (ON) for about 5 seconds until you hear a sound. Make sure the green led light turns on. Then, put water in the installation location and saturate the surrounding land in a radius of at least 10 centimeters around the sensor.
