A: You can choose between the 10K ohm or 100K ohm versions, which is the resistance measured at 25°C. Both models have a B-value of 3950, which you'll need for the formula to convert its resistance reading into a temperature.. Q: What are the probe and wires like on this thermistor? A: The sensor itself is a small bead that is sealed in epoxy resin to protect it from moisture. The attached wires are insulated and flexible, making it simple to place the sensor where you need it in your project.. Q: How do I use this to measure temperature with a microcontroller? A: The most common method is to use it in a voltage divider circuit with a fixed-value resistor. You then connect the center point of that circuit to an analog input pin on your Arduino or ESP32 to read the voltage changes as temperature fluctuates.. Q: What's the main advantage of getting a thermistor with wires already attached? A: It saves you the difficult and delicate task of soldering wires onto the tiny component leads. This makes them much quicker to implement, especially for testing on a breadboard, and reduces the risk of damaging the sensor with heat.. Q: How accurate are these temperature sensors? A: These thermistors have a resistance tolerance of ±1%. This level of precision is very good for most hobbyist electronics, 3D printer hotends, or general-purpose temperature monitoring projects..
