Knowing the parts and tools to build your sensor

In this section, we will look at each part you can use to build your double measurement sensor. You will understand the purpose of each so that you can integrate them using a provided electronic circuit, something that we’ll do later in this chapter. We will frequently reference the Sensors section in Chapter 1 and the block diagram shown in Figure 1.9 of that chapter.

Each description isn’t meant to provide deep details about how each part works but just the information required so that you can build a sensor or make some important adjustments or configurations so that the final circuit can work according to its intended use.

To build the double measurement sensor, you will need the following electronic parts and components:

• HC-SR501 motion sensor
• BMP280 environmental sensor module
• ESP8266 Wi-Fi module
• USB cable (USB Type A to USB Type B micro)
• USB adapter (IN: AC 100 ~ 240V/OUT: 5V @ 1A)
