Immediate stock of common sensors for projects and production
When a prototype deadline, lab class or service call is looming, waiting weeks for components isn’t an option. Communica keeps a broad local stock of sensors - temperature, humidity, pressure, PIR, ultrasonic, light, current, MEMS IMUs and common environmental modules - so South African makers, students and procurement teams can move from design to testing the same week. Local availability reduces lead times, simplifies VAT invoicing for institutions, and lets you collect from Samrand or our branches in Pretoria and Cape Town.
Why local stock matters for real projects
Buying sensors locally avoids surprise delays, gives access to accessory bundles (breakout boards, headers, enclosures) and makes returns or warranty administration faster. For education labs we routinely supply teaching quantities and can include packing lists for purchase orders and quotes.

Common sensor types we keep in stock
- Temperature & humidity modules (digital and analog)
- Pressure sensors and barometers for altimetry and HVAC
- Proximity and distance (ultrasonic, ToF, IR)
- Motion: accelerometers, gyros and PIR motion detectors
- Environmental: gas, VOC, CO2-focused modules
- Electrical: Hall-effect current sensors and AC/V sensing
Specification callouts & compatibility guidance
When comparing modules, start with these practical checks: supply voltage (3.3V vs 5V), interface (I2C, SPI, analog), sampling rate, and whether the breakout includes level shifting. For microcontroller projects, prefer sensors labelled as 3.3V-friendly to avoid extra regulators. If you need help confirming compatibility, check our brand index for common pairings: Shop by Brand.
