Why choose Communica for sensor ICs
Find sensor ICs quickly and with confidence. Whether you are a university lab designing a prototype, a technician repairing instrumentation, or a maker building an IoT node, Communica keeps popular MEMS, environmental, magnetic and proximity sensor ICs in local stock so you can move from idea to test fast. Local pickup from Samrand and our branches shortens lead times and simplifies project scheduling.
Local benefits that matter
- Immediate branch collection from Samrand, Pretoria CBD or Cape Town to avoid long import delays.
- VAT invoices and account quoting for educational departments and procurement teams.
- Technical selection guidance and recommended accessory bundles for quick prototyping.

Common sensor IC types and when to use them
Below is a practical catalogue-style guide to the sensor types engineers request most often. Use it to map a project need to a specific IC family and accessory set.
| Sensor Type | Typical Use | Common Packages |
|---|---|---|
| Accelerometers / Gyros | Motion sensing, inertial navigation, gesture control | QFN, LGA, breakout modules |
| Pressure / Barometric | Altitude, flow measurement, weather stations | SOIC, LGA, modules with port |
| Temperature / Humidity | Environmental monitoring, HVAC control | SOT-23, DFN, breakout boards |
| Magnetic (Hall) | Position sensing, brushless motor feedback | SOT-23, SSOP, modules |
Quick selection checklist
- Signal interface: I2C and SPI are common - match MCU availability.
- Supply voltage: choose ICs compatible with your rail (1.8V, 3.3V, 5V).
- Package and mounting: pick breakout modules for breadboard prototyping.
- Noise and bandwidth: higher bandwidth for motion capture, lower noise for precision sensing.

Specification callouts and compatibility guidance
When comparing datasheets, prioritise these specs to avoid surprises during integration:
| Spec | Why it matters | Practical tip |
|---|---|---|
| Voltage range | Determines direct connection to your MCU rail | Prefer sensors compatible with 3.3V systems common in Raspberry Pi and many MCUs |
| I2C address options | Avoid bus conflicts on multi-sensor setups | Choose parts with address pins or use I2C multiplexers |
| Noise / Resolution | Impacts measurement precision | Match to the measurement goal - e.g., ±2g accelerometer vs ±16g |
