This is an IoT device to remind my dad watering my mom’s plants when she is not at home. It works by detecting moisture in the plant soil. If there is sufficient soil water, all 3 LEDs will keep lighting. As soil water becomes more and more insufficient, the LEDs will fade away. And if the plants are out of water, there will be only one LED light and IFTTT will immediately send out a SMS message to my dad. Also there is a switch to disable/enable the soil moisture.
