There seems to be a race on Amazon as to who can get the most sensors into a kit. Previously we looked at Kookye’s 16 Sensor Kit and really liked what they offered. Today we are looking at Elegoo’s 37 in 1 Sensor Kit. Now it’s not quite fair to say this kit is 21 better than the other kit because its goal is very different. While they do share some of the same sensors, the Kookye kit is designed to introduce the user to sensors that could be used in IoT situations, Elegoo’s 37 sensor kit aims to teach the electric theory behind the sensors and give a wide understanding of the number of options that you have for Arduino-real world interaction.
Before we get into the tutorials and philosophy behind this kit, let’s look at the practical side of things:
- Case is nice hard plastic
- All modules have their own compartment
- Full color picture packing list and organization guide, it’s your fault if you lose track of these.
- All sensors have male headers to make connections easy.
Honestly some of the modules seem like Elegoo was really trying to stretch for 37. For example, some of them take a 3 pin device, connect it to a PCB and output to a 3 pin male header. Several of these are different sensors mounted to the same PCB. But for less than $1 per module this shouldn’t bother you (even of one of the modules happens to be a button, yep just a button-on a PCB.)
The beauty of this kit is its goal of teaching the theory and not just a demonstration of the device. There are 26 lessons included on the CD and working through all of them would take some time. Each lesson is divided into several parts: a detailed explanation of what the sensor is and how and why it works, the schematic, and the instructions to plug it in and run the code. As detailed as the how and why is, that is how little information is in the plug and run section. The English isn’t great, but for the most part it is understandable. The good news is all of the code snippets work and these will get most people well on their way to using these devices in their own builds. There are several things here that I would have never thought of interfacing with an Arduino before (like the laser, the reed switch, or the InfaRed heartbeat detector) some things that would be right at home on a robot (like the line detector, the IR avoidance sensor, and the sound detectors) and some things you’d need in a smart house (like the temperature, humidity, light sensor, and the relay.) Like most of the starter kits, this is more for you to get your feet wet and discover than it is for you to make a finished product. With that said you could use these in larger projects. Check out how we used the laser and joystick in our most recent tutorial.
This is a great kit for learning what’s out there and how to use it. You would be well served if you started with Elegoo’s Beginner Kit and moved to this one when you finished with those tutorials.
