Chapter 4: Fun with Gardening!
In this chapter, we will discuss interfacing a soil sensor to a Raspberry Pi Pico and publishing the soil moisture and temperature values to ThingSpeak (https://thingspeak.com), an Internet of Things (IoT) platform that enables you to visualize collected data. By the end of this chapter, you should be able to build something like this:
Figure 4.1 – Fun with gardening
In the preceding photo, a STEMMA soil sensor from Adafruit Industries is inserted next to a small potted plant. The soil sensor is interfaced to a Raspberry Pi Pico. The Pico is mounted onto a Dual Expander pack. A Pico wireless pack is interfaced to the left of the Pico for uploading soil moisture values to ThingSpeak.
We are going to discuss the following topics in this chapter:
- Why gardening?
- Installing the requisite libraries
- Setting up the soil sensor
- Setting up the wireless pack
- Setting up the NeoPixel light-emitting diode ...
