Reliable local ordering for temperature sensing devices
Finding the right temperature sensing device and ordering online in South Africa requires clear specification, quick stock checks and the option to collect or invoice locally. Communica stocks a broad range of temperature sensors and probe assemblies suitable for hobbyist, educational and industrial projects - from simple NTC thermistors and waterproof probes to digital I2C/OneWire modules and precision semiconductor sensors. Use this page to compare common types, confirm local availability, and choose accessories and mounting options that match your application.
Why order from a local distributor
Ordering locally reduces lead times, simplifies VAT invoicing for institutions, and allows branch pickup in Samrand, Pretoria CBD or Cape Town. For branch locations and trading hours see the branches page here. If you want to browse categories, the collections index is a helpful starting point here.
Common temperature sensor types
- NTC thermistors - low cost, good for temperature sensing in hobby and classroom projects.
- PT100/PT1000 RTDs - higher accuracy across wider ranges, used in lab and industrial settings.
- Semiconductor sensors (e.g., LM35, TMP36, digital I2C/OneWire) - easy interface with Raspberry Pi projects.
- Thermocouples (Type K, J, T) - wide temperature range for industrial and HVAC uses (requires amplifier/conditioner).
- Waterproof probe assemblies - stainless probes with cable for immersion or outdoor use.
| Type | Typical Range | Accuracy | Good for |
|---|---|---|---|
| NTC Thermistor | -50 to +150°C | ±0.5-2°C | Prototyping, hobby, enclosures |
| PT100 / PT1000 RTD | -200 to +850°C | ±0.1-0.5°C | Lab, HVAC, industry |
| Semiconductor (Analogue/Digital) | -40 to +125°C | ±0.25-1°C | Microcontrollers, education, IoT boards |
| Thermocouple + Amplifier | -200 to +1800°C (type dependent) | ±1°C and better with calibration | High-temp, furnaces, engines |
Specification callouts to check before ordering
- Temperature range and required accuracy for your application.
- Output type (analogue voltage, resistance, digital bus like I2C or OneWire).
- Supply voltage and interface level compatibility with Arduino, Raspberry Pi or industrial PLCs.
- Probe form factor, cable length and ingress protection if used outdoors or in liquids.
Pro tip: For education and makers, modules with built-in pull-ups and clear datasheets speed integration. Browse Communica's product index to compare specific items where to find temperature sensing devices online.

Compatibility, accessories and ordering options
Choosing compatible accessories simplifies deployment. Common add-ons include thermocouple amplifiers (e.g., MAX31855/MAX6675), RTD-to-digital converters, waterproof probe housings, terminal blocks and connector pigtails. When ordering online, check if a sensor requires a separate breakout or cable - Communica lists parts across brands and categories on the shop by brand page here.
Specification examples and quick calculations
For analogue thermistors and semiconductor sensors, convert output to temperature in your microcontroller. Use Ohm’s law and a voltage divider for NTC measurements:
Vout = Vin * (Rfixed / (Rfixed + Rntc))
Measure Vout with the ADC and map to resistance, then use the thermistor curve or B-parameter equation to find temperature. For digital sensors like DS18B20, the device returns temperature directly over OneWire with minimal conversion.
Stock, lead times and procurement for South African buyers
Communica maintains local stock for many popular sensors and modules, which helps reduce lead times compared to importing. For larger institutional orders or procurement teams, request a quote to get VAT invoices and delivery timelines. You can check stock levels and branch pickup options on the homepage and collections pages: Communica homepage and collections.
Compatibility checklist before you order
- Confirm interface matches your controller (ADC range, I2C address, OneWire bus).
- Check supply voltage and required pull-up resistors for digital buses.
- Choose appropriate enclosure and probe length for the mounting environment.
- Plan for calibration if the application requires higher accuracy; budget for calibration accessories if needed.
