Soil Moisture Sensor FAQ

Watch this 2-minute video by Chris Thorup, co-founder of Spiio, where we also briefly show how the SP-110 is turned on and installed.

  • How does SP-110 connect?

    It connects like your cell phone through cellular 3G/4G network providers. The SP-110 will automatically find the strongest network provider in your area and use their network to transmit data. Check if we cover your country here.

  • How long does the battery last?

    The SP-110 holds battery for an average of 5 years.

  • How often does the SP-110 send data?

    The SP-110 is sampling data every hour and transmitting it to you every fifth hour. We can change the sending frequency depending on your preferences but note that it impacts the battery lifetime – positively or negatively.

  • Will the SP-110 be damaged by rocks and gravel?

    It can take some hits, but it varies from case to case. We have protected the sensor probe as much as we can so it can withstand scratches without damaging the soil moisture sensor.
