Sensors

Build smarter projects with sensors from Circuitrocks. From temperature and humidity to motion, distance, gas, IMU, GPS, and biometrics, this collection covers the essentials for Arduino, ESP32, and Raspberry Pi. Most modules support I2C/SPI/UART/analog interfaces and work at 3.3–5V for fast prototyping in classrooms, labs, and production.

Pick modules that match your wiring style and MCU pins:

Recommended Essentials

Compatibility Notes

  • Voltage: Arduino Uno uses 5V logic; ESP32/Raspberry Pi use 3.3V—use a level shifter if needed.
  • Addresses: For I2C, confirm default addresses & jumpers if you’re chaining multiple sensors.
  • Libraries: Most product pages link to Arduino/PlatformIO/MicroPython libraries and example code.

FAQs – Sensors (Philippines)

Are these sensors compatible with Arduino, ESP32, and Raspberry Pi?
Yes. Most use I2C/SPI/UART/analog and work on 3.3–5V. Match voltage levels to your board or add a level shifter for safety.
Do you offer starter bundles for classrooms or labs?
Yes—see our sensor kits and Arduino/ESP32 bundles. We also support academic bulk orders.
How do I calibrate sensors like load cells, gas, or pH?
Follow the calibration steps on each product page (e.g., HX711 reference weight, gas sensor burn-in, pH two-point calibration). Libraries and examples are linked per item.
Do you ship nationwide in the Philippines?
Yes. We ship nationwide via trusted couriers, with fast dispatch for Metro Manila orders.
