      My son has become really curious about sensors and smart systems since using the Havi’s sensor kit. He’s asking so many questions and can relate his projects to real-world systems. It’s been great to see him so engaged and learning!

      As a teacher and a sports coach, I’m always on the lookout for tools that can merge my two passions and engage my students. The Object Sensor Projects Kit did just that. Not only did it introduce my students to the fascinating world of robotics, but it also incorporated sports-themed projects like the smart basketball hoop. Seeing their faces light up as they successfully completed each project was a home run moment for me. This kit is a must-have for any educator or parent looking to score big with their budding sports-loving technologist!

      The snap-fit electronic blocks made it easy for my son to assemble the projects without needing much help. The projects themselves were engaging and varied, from a smart basketball hoop to a touchless doorbell. It’s a great way to introduce kids to STEM concepts in a hands-on way.

      As a parent, I’m always looking for educational toys that are both fun and informative. This Object Sensor Projects Kit exceeded my expectations. My child not only had a blast building the projects but also gained a deep understanding of IR sensor concepts. The included worksheets were incredibly helpful in reinforcing what they learned. Highly recommend for any budding roboticist!

      Contents look good and I am sure kids will have fun assembling the projects. Appreciate the time your team has put in. Always wondered how to get my kids interested in electronics and your project kit seem to be the perfect way to do it.

      You can work on the slots for various parts in the box for packaging. That would keep things in good shape.
      But overall, much recommended..!

        Sure, we will improve on inner slots of packaging.
