Maker Line is a line sensor with 5 x IR sensors array that is able to track line from 13 mm to 30 mm width.
The sensor calibration is also simplified. There is no need to adjust the potentiometer for each IR sensor. You just have to press the calibrate button for 2 seconds to enter calibration mode. Afterwards you need to sweep the sensors array across the line, press the button again and you are good to go.
The calibration data is saved in EEPROM and it will stay intact even if the sensor has been powered off. Thus, calibration only needs to be carried out once unless the sensor height, line color or background color has changed.
Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently, which is similar to conventional IR sensor, but you get the benefit of easy calibration, and also one analog output, where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required while building a line following robot with PID control.
Features
Operating Voltage: DC 3.3 V and 5 V compatible (with reverse polarity protection)
Recommended Line Width: 13 mm to 30 mm
Selectable line color (light or dark)
Sensing Distance (Height): 4 mm to 40 mm (Vcc = 5 V, Black line on white surface)
Sensor Refresh Rate: 200 Hz
Easy calibration process
Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position.
Support wide range of controllers such as Arduino, Raspberry Pi etc.

Developing CoAP applications for Thread networks with Zephyr
This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on:
The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4.
Network simulation with the OpenThread Network Simulator.
Connecting a Thread network to a non-Thread network using a Thread Border Router.
The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network.
The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses.
The process of joining a Thread network using network commissioning.
CoAP servers and clients and their OpenThread API.
Service registration and discovery.
Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates.
Investigating and optimizing a Thread device’s power consumption.
Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.

Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards.
Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components.
With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.

The JOY-iT R301T fingerprint sensor module is capable of image collection and algorithm calculation due to this integrated chip. Another remarkable function of the sensor is, that it can recognize the fingerprint in different conditions, for example humidity, light texture or changes of the skin. This offers a very wide range of possible applications to secure locks and doors among others. The chip can send data via UART, TTL serial and USB to the connected controller.
