Abstract:

This paper presents water quality monitoring IoT Beat Sensors. The interval times of ID code transmitted

wirelessly from Beat Sensor nodes correspond to amount of salinity, water levels, and pH, so that receivers

can acquire these parameters from many sensor nodes in agriculture and aquaculture fields. In experiments,

this system can measure salinity in the range 0.58%~6.48% with an average power consumption of 500uW,

water level in range 3.5~10.5cm with average power consumption of 90 uW and pH in range 3.45~9.58 with

average power consumption of 70 uW.

SUMMARY

IoT automation requires programming platform that can connect with all the sensors. This plat-

form must be compatible with the sensors and able to program them. This platform should not

be dependent on any other external system in order to work. Two such platforms exist today

known as Arduino and Raspberry Pi, which are not only reasonably priced but also provide

all the necessary components to connect with the available sensors. These two platforms are

equally capable of performing various tasks and create wearable and non-wearable standalone

IoT solutions.

In this chapter, we have learnt the following:

• How Raspberry Pi despite being small became popular due to its plethora of features at

a low-price.

• Raspberry Pi contains all the basic PC components, and it can work well for basic

computing tasks.

• How Raspberry Pi has been used to steer young children towards computer science.

• How Raspberry Pi can help differently-abled people with various tasks.

• Arduino is an open-source programmable board used for software and hardware

projects.

• Arduino boards contain all the basic computer components.

• Arduino IDE is used for incorporating functionality to the Arduino board.

• Arduino programming begins with basic programming concepts and has built-in

functions to support hardware operations.

In the next chapter, we will explore various real-life project ideas that you can implement

to gain hands-on experience. All these ideas are taken from various dierent industries so you

will get a broader picture of IoT benefits in various dierent industries.
