What’s 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 have only used two sensors, which only offer three parameters, but there are a lot of sensors on the market that provide a wide variety of functionalities, such as air pressure and measurements for different gases.

Try out the following sensors to enhance your practical knowledge and compare them with other sensors in terms of features, range, and cost:

• The BMP280 (pressure and temperature) sensor
• The MH-Z19C/D/E series sensors for carbon dioxide monitoring
• The MQ series sensors, which are designed to sense different specific gases, including MQ-2, MQ-3, MQ-4, MQ-5, MQ-7, MQ-8, and MQ-9
• Seeed Studio SCD30 (temperature, humidity, and CO2)
• Gravity: Analog Electrochemical Carbon Dioxide Sensor (0–10,000 PPM)
