Sensors / Temperature / Analog / Thermistor

Need to measure something damp? This epoxy-coated precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in 25 °C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it gets cooler. For specific temperature-to-resistance, check the lookup table. These are often used for air...

Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage...

For fans of the TMP36, we now have a very similar analog temperature sensor with a 3-pin JST connector (we call these STEMMA connectors). Unlike many of our temperature sensors, this one is analog output, not I2C, so its best used by a microcontroller with an analog input, as most microcontrollers do. These sensors are very simple to use, no libraries or complex...

An assortment of the most common sensors used in electronics. 9 sensors and 3 additional components to interface with the 'analog world'. We have some tutorials here, to get you started. Includes Triple-axis analog accelerometer - for measuring motion and tilt. Force sensitive resistor - for sensing pressure/force. Temperature sensor - for measuring from -40 to over...

Need to measure something with a very slim sensor? This precision 10K thermistor is an inexpensive way to measure temperature in a small gap, or taped to a flat surface, it's only 0.2mm wide! The resistance in 25°C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it gets cooler. For specific temperature-to-resistance, check the lookup...
