What next?
We still have a lot of options available to explore, but now it’s your turn to use different sensors and development boards to do some more experiments and learn from them. In this chapter, we used 10 sensors but only 3 different types, that is, moisture, temperature, and outdoor temperature and humidity. However, on the market, there are a lot of sensors that provide a wide variety of functionalities for soil, such as NPK (which stands for nitrogen, phosphorus, and potassium), EC (which stands for electrical conductivity), and pH sensors and different gas sensors for outdoor measurement.
Try the following sensors to enhance your practical knowledge and compare them with other sensors in terms of features, ranges, and cost:
- NPK sensor
- Soil EC sensor
- Soil pH sensor
- MQ series sensors, which are designed to sense specific gases, including MQ-2, MQ-3, MQ-4, MQ-5, MQ-7, MQ-8, and MQ-9, to find the correlation of gases and their effects on soil and...
