Communica's Samrand stockroom carries these sensor styles in multiple package forms (probe, SMD, module) from brands such as Murata, ABB, Amphenol, Adafruit, and many more. Selection factors include accuracy, response time, range, and interface (analog or digital). VAT invoices and account quotes are available for business and education planning.
How to Select a Temperature Sensor for Your Application
- Define the target temperature range (e.g., -40 degreesC to 125 degreesC for industrial controls; 0 degreesC to 70 degreesC for indoor monitoring).
- Determine required accuracy (e.g., Pt100 RTDs for 0.1 degreesC, thermistors for 1 degreesC in general use).
- Choose a sensor interface: analog voltage (LM35, thermistor), digital one-wire (DS18B20), or I2C/SPI bus (MCP9808, Adafruit modules).
- Check sensor packaging: bare bead, sealed probe, SMD, or pre-mounted module depending on your assembly needs.
- Review available stock levels and lead times at Communica Samrand to match your project timeline.

Specifications and Real-World Examples
When calculating or specifying a temperature sensor, consider:
- Thermistor Equation: The Steinhart-Hart equation is used to convert thermistor resistance to temperature. For an NTC thermistor:
1/T = A + B * ln(R) + C * [ln(R)]3
where T is temperature (Kelvin), R is resistance (Ohms), and A, B, C are calibration constants on the datasheet.
- RTD Linearity: RTDs are very linear. For Pt100:
Rt = R0 * [1 + alpha(T)]
where alpha ~ 0.00385/ degreesC and R0 is 100 Ohm at 0 degreesC.
- Digital Sensors: Sensors like DS18B20 deliver temperature as a digital value. Use libraries for platforms like Arduino or Raspberry Pi to enable fast integration.
Application Notes: Industry and Maker Use Cases
- Industrial OEMs source RTDs for production lines directly from Samrand with immediate VAT-compliant invoicing.
- Students easily prototype greenhouse controllers with digital sensors (DS18B20) mounted on breadboards from the Communica range.
- Maintenance teams pick up replacement thermistors for on-site service with minimal downtime, leveraging local stock availability.
Troubleshooting Common Sensor Challenges
- Ensure wiring is correct: Follow color codes and datasheets when using multi-lead RTDs or thermocouples.
- Shield digital sensors' data lines where EMI is present (factories, HVAC plants).
- Verify pull-up resistor values for one-wire sensors like DS18B20-usually 4.7k to 10k to 3.3V or 5V rails works.
- Check module input voltage ratings, especially when integrating with 3.3V microcontrollers (e.g., Raspberry Pi vs Arduino).
