The display panel shows the relative magnitude of conductance (reciprocal of resistance) between the two test probes when these are inserted in the soil. The tester measures the dryness or wetness through soil resistance readings (0 to about 5 kilo-ohms) and indicates in dot mode by sequential lighting of LED1 through LED8.

Good book but not shipment safe.
Format: Board book
I love the book but the shipment left bumps on all corners. It saddened me :( considering an international shipment they should've been more careful.

Fun animal book with Eric Carle illustrations!
Format: Board book
Some of the noises the animals make feel a little strange, but my toddler loves to push the buttons! I do like that it says the name of the animal before making the sound the animal makes - gives some vocabulary practice when my daughter is reading independently.
