Thermocouple Type-K - Stainless Steel
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 ...

Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long
For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small st...
Electric Heating Pad - 14cm x 5cm
A flexible electric heating pad made from stainless steel fibre fabric. Apply 5–12V DC and it warms up — temperature varies with voltage. Lightweight and flexible enough to wrap around objects or integrate into wearable projects. Essentially a large flexible resistor, it can be driven with PWM v...
DHT11 basic temperature-humidity sensor + extras
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing t...
