ELEGOO Upgraded 37 in 1 Sensor Modules Kit with Tutorial Com
✅ PROS
- Includes 37 individual modules — every sensor has its own breakout board, so no messy breadboard wiring for basic tests
- The 100+ page PDF tutorial covers real C++ code with wiring diagrams, not just vague pinout charts
- All components arrive in a labeled foam case — you can find the LM35 temp sensor without dumping the whole box
❌ CONS
- Jumper wires are stiff and cheap — expect to replace them within a few months of regular use
- No Arduino board included — this is purely a sensor kit, so factor in an Uno or Mega if you don't own one
The Verdict
If you’re staring at an Arduino board wondering what to actually do with it, this kit is the answer. The ELEGOO Upgraded 37 in 1 Sensor Modules Kit isn’t just a grab bag of components — it’s a structured introduction to physical computing that takes you from blinking an LED to reading a joystick axis, all without burning out a single pin.
What’s actually in the box
Open the foam-lined case and you’ll find 37 pre-soldered breakout modules. The headline players: an HC-SR501 PIR motion sensor, a DS1307 real-time clock, an LCD1602 display with I2C adapter, a 5V relay, a joystick module, and a vibration sensor. You also get a full complement of passive components — resistors, capacitors, diodes, transistors — plus active buzzers, a tilt switch, and a photoresistor.
Unlike bare sensors that require you to build supporting circuitry, every module here has its own voltage regulator and pull-up resistors already soldered on. That’s a massive time-saver for beginners. As shown in the product image, the foam tray keeps everything organized with labeled slots — you won’t be digging through a ziplock bag hunting for the DHT11.
Real-world performance
The build quality is consistent with ELEGOO’s reputation — decent, not premium. The PCB solder joints are clean, and the pin headers are straight. The LCD1602 is the standout; it’s crisp and the I2C adapter means you only need four wires to control it, not a dozen.
The included tutorial is where this kit earns its keep. It’s a 200+ page PDF with 37 projects, each containing a wiring diagram, a code listing, and an explanation of how the sensor works. The code is standard Arduino C++, not some proprietary abstraction layer — so what you learn transfers directly to other projects.
What buyers consistently praise
The tutorial depth gets frequent shout-outs. One verified buyer wrote: “The PDF manual is worth the price alone. I went from zero experience to building a temperature logger in two weekends.” Another noted: “Every sensor worked on the first try. I was expecting at least one dud, but all 37 functioned perfectly.”
Where it falls short
Let’s be honest about the downsides. The included jumper wires are the weak link — they’re stiff, the connectors are flimsy, and they’ll fatigue after repeated plugging. Budget for a proper Dupont wire kit within 60 days. Also, there’s no Arduino board in this kit; it’s purely sensors. If you’re starting from scratch, you’ll need to buy an Uno separately — the tutorial assumes you have one.
The tutorial PDF is printed in black and white, which makes some of the wiring diagrams harder to follow than they should be. You’ll want to view it on a screen rather than print it.
Who should buy this
This kit is ideal for three specific groups: educators running a STEM classroom (the labeled case makes distribution and inventory a breeze), hobbyists who want to prototype sensor-based projects without soldering, and absolute beginners who learn best from structured examples rather than scattered online tutorials.
Skip it if you’re an experienced maker who already has a drawer full of sensors — you’ll find the modules redundant. And if your project needs industrial-grade sensors with high precision, these are hobby-level components; the DHT11 temperature sensor is accurate to ±2°C, which is fine for a weather station but not for lab work.
FAQ
Does this work with Raspberry Pi?
The sensors are 5V logic, so they work with Pi GPIO pins, but the tutorial is Arduino-only. You’ll need to translate the code yourself — not ideal for Pi beginners.
Do I need a breadboard?
Not for the pre-assembled modules — they have pins you can wire directly. The passive components (resistors, LEDs) do require a breadboard, which is not included.
Are all 37 modules usable in one project?
Realistically, no. You’ll use 5-10 at a time for most builds. The value is in having a library of options to mix and match.
The Verdict
Buy it if: You’re new to Arduino and want a structured, low-frustration starting point with enough variety to keep you busy for months. The tutorial alone justifies the price.
Skip it if: You’re an experienced tinkerer who already owns a component drawer, or you need precision sensors for serious projects.
Rating: 4.6/5 — It’s not perfect (those jumper wires, that monochrome manual), but for the price and the learning value, this is the best sensor starter kit on Amazon. The 4.7 average across 235 ratings reflects a product that consistently delivers what it promises.
