What are the application scenarios for temperature and humidity sensors?
Temperature and humidity sensors integrate temperature and humidity measurement into a single unit. Depending on the specific environmental conditions, different types of sensors are required. When selecting a sensor, it is essential to identify the object being measured and the desired measurement range, which typically spans from –40°C to 85°C.

What are the performance characteristics of a thermistor?
Thermistors have the following advantages: ① High sensitivity. The temperature coefficient of resistance (α) of a thermistor is 10 to 100 times greater than that of metals, allowing the use of lower‑precision indicating instruments. ② High resistance value. Its resistance is 1 to 4 orders of magnitude higher than that of platinum resistance thermometers. ③ Small size and simple structure. They can be fabricated into various shapes as needed; the smallest bead‑type thermistors currently available measure as little as Φ0.2 mm and are commonly used for measuring “point” temperatures. ④ Short response time.

What is the Class A accuracy of a household appliance temperature sensor?
Temperature sensor with Class A accuracy; temperature tolerance: ±(0.15°C + 0.002|t|). The resistance values can be converted according to the respective graduation number. For example, for PT100, the resistance at 0°C is ±0.059 Ω, and at 100°C it is ±0.133 Ω.
