SKU: TB-RN3436

A 1 kΩ NTC (negative temperature coefficient) thermistor in a 5 mm radial dipped-epoxy package. The resistance decreases as temperature increases, making it suitable for temperature sensing, thermal compensation, and monitoring applications. Rugged ceramic construction with tinned copper leads fo...

SKU: TB-RN3442

A 47 kΩ NTC (Negative Temperature Coefficient) thermistor in a compact 5 mm radial package. NTC thermistors decrease in resistance as temperature rises, making them ideal for temperature sensing, thermal protection, and compensation circuits. Dipped in epoxy for durability, this through-hole com...

SKU: LB-00257

We’ve all seen toys and things that change color when you run them under warm water or heat them up in the sun. Some of us were especially mesmerized and had to find out what made them do that. It turns out that this is a property called “thermochromism” and it can be implemented in a number...

SKU: AF-4137

We love playing with obscure materials that have a creepy-cool or magical quality. Sure, there's invisible ink, but have you ever used heat to make a painting disappear?We're carrying these Thermochromic Pigments in a variety of colors. This pigment is a bright Yellow. It changes to a light/white...

SKU: AF-269

The MAX31855 Thermocouple Amplifier Breakout converts K-type thermocouple readings into digital data via SPI, handling cold-junction compensation automatically. It measures temperatures from −200°C to +1350°C in 0.25°C increments, making it suitable for a wide range of temperature monitoring appl...

SKU: AF-1727

The MAX31850K breakout board is a 1-Wire thermocouple amplifier with cold-junction compensation for K-type thermocouples. Unlike SPI-based amplifiers, the 1-Wire interface allows any number of thermocouple breakouts to share a single data line — ideal for multi-point temperature measurement. The...

SKU: SF-PRT-13612

This Thermocouple Connector is perfect for bridging the gap between Type-K thermocouples with standard connectors with a PCB. This little connector is actually the exact part we recommend using with our SparkFun Thermocouple Breakout! Each connector can easily attach to a printed circuit board...

SKU: AF-3895

Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare-wire bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200°C, this one uses a fiberglass braid so it can be used ...

SKU: SF-SEN-00251

36" high temperature Type-K Thermocouple with glass braid insulation.

SKU: AF-270

A Type-K thermocouple with fiberglass braid insulation, rated to 500°C — far beyond the ~200°C limit of standard vinyl-insulated thermocouples. The bare bead probe design is suited to measuring both air and surface temperatures in high-heat environments such as ovens, kilns, heaters, and industri...

SKU: AF-3245

Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare wires stainless-steel tip probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200°C, this one uses a fiberglass braid so...

SKU: SF-SEN-13715

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). Once this is achieved, a voltage potential is ...

SKU: SF-COM-15082

Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature dif...

SKU: SA-663616

This detailed Solar System figurine set includes the Sun and all eight planets, each with accurately painted colours and surface features — from Jupiter's storms to Saturn's rings and Earth's polar ice caps. The set comes with an acetate tray that shows the planets in their correct orbital positi...

SKU: PI-EMS-555

Re-create one of the most iconic chips in electronics history. The Three Fives Kit from Evil Mad Scientist Laboratories is a faithful, functional transistor-scale replica of the classic NE555 timer IC — built up from individual resistors, 2N3904 and 2N3906 transistors on an oversized PCB shaped l...

SKU: PI-EMS-762

Build a working transistor-scale replica of the classic and ubiquitous analog workhorse. The "XL741" Discrete Operational Amplifier kit from Evil Mad Scientist Laboratories is a faithful and functional transistor-scale replica of the μA741 op-amp integrated circuit, the classic and ubiquitous ana...
