About Sensor & Antenna Range
Terra comes with Blu Series, 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 Blu Series 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 Blu Series antenna allows you to place sensors further away, and also pick up Blu Series-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.
