Panda Plant Guardian Kit

This panda-shaped gadget has a pair of soil probes that measure how damp the soil is. The kit is very easy to build and, once finished, it goes straight into the pot of your favourite houseplant. The bright RGB LEDs that stand in for the panda’s eyes light up every 30 seconds to show the state of the soil: just right, too wet or too dry. Since every plant has different needs, the kit lets you adjust the moisture range and the sensitivity. The kit runs on two CR2032 batteries (not included), which keep the panda alive for at least two full months.

• probes that measure the moisture level
• 2 rotary trimmers to set the range and the sensitivity
• 2 RGB LEDs that show the moisture level every 30 seconds:
• fun panda-shaped PCB
