Chapter 10: IoT Plant Pot Moisture Sensor

With the advent of the Internet of Things (IoT), we are immersed in the new industrial revolution—the so-called Industry 4.0. One of the industries that have benefited the most from these technologies is agriculture (Chalimov, 2020). Agricultural IoT applications range from autonomous harvesting to sensors to recognize pests and diseases or to measure humidity. We can take advantage of these advances in our homes—for instance, monitoring our ornamental plants to have more efficient care.

In this chapter, you will put into practice information learned in Chapter 9, IoT Temperature-Logging System, about how to connect and program an internet connection, but this time we will introduce a NodeMCU microcontroller to facilitate the ESP8266 programming. You will learn how to create a digital device to monitor a plant pot, reading data from a soil moisture sensor and determining whether it needs water, and then sending an alert to...
