This project describes adding temperature and CO2 sensors to a mobile robot to sense and alarm when values in the environment exceed a given threshold.
Type: Commercial, Social Impact, Education
I wanted to find a way to teach young people about basic robotics and electronics that had a real-world application that wasn't too difficult to implement. The SparkFun Inventor's Kit and Qwiic Connect sensors provided an easy way to do these things even for novice makers.
It is about using a robot to detect changes in temperature or CO2 in an environment. It is essentially an environmental sensing robot that determines changes in a home environment to alert the family living there. If the temperature exceeds a certain threshold it spins one way, if it exceeds a CO2 threshold it spins another way. Ways to enhance this project include adding an audible alarm such as a buzzer and another visual alarm such colored LEDs.
How to attach and use Qwiic Connect sensors on an Arduino Uno to read and detect changes in a robot's environment by using proprioceptive sensors.
It is a great way to introduce young people to electronics and robotics including sensing, planning, and acting. It is also a great way to teach them basic programming and provides a way for them to appreciate how being a maker and doing STEM can enable them to create things to improve the world and help people.
