The next best garden tool to a shovel, the Soil Sensor is a compact device that you can insert anywhere in your garden or yard. It will continuously update your Terra with the soil temperature, moisture level and amount of light received. Wonder if a spot is too sunny or shady for that plant? Not sure if you need to water today? Or maybe if the soil is warm enough to start planting in the spring? Use them wherever you want your plants to thrive, and watch your thumbs turn green!
About Range
Terra comes with bluetooth, wifi and MOTUS antennas built in - the external antennas are to boost range. We’d like to be able to give exact numbers about ranges with and without antennas, but it’s very dependent on where the Terra/sensors/wifi network are, and what physical barriers there are in the environment (trees, house walls, etc).
As a rule, the Terra is built to work out of the box with your wifi network if it’s placed in a yard, garden etc. The bluetooth should also work in an average size yard. The MOTUS antenna has a range of at least .5km, and probably much further with open sky.
That said, if your wifi network is weak, or if you are placing the Terra further away from the house, then the wifi antenna will help. Likewise, the bluetooth antenna allows you to place sensors further away, and also pick up bluetooth-tagged Monarch butterflies at greater distances. Finally, the MOTUS antenna will actually increase your range to that of a professional sensor station, approx 2-10km depending on placement.
