Growing plants indoors is going to be much easier when you have a smart plant sensor to give you feedback on soil moisture, light level, and other factors. The FYTA Beam fits the bill. It connects your plants to your smartphone, so you will be able to detect when your plants need water, fertilizer, and light.
To get started, insert the sensor into the soil and install the FYTA app. You can connect 4 Beam sensors with Bluetooth LE Mesh with a range of 100m. These sensors can read soil moisture/fertility, light intensity, and ambient temperature. The companion app can identify plants and show you how to take better care of them.[where to get it]
