Tips: Uses of NTC temperature sensors with different resistance values

• 5kΩ~10kΩ: NTC temperature sensors with 5kΩ~10kΩ are suitable for medium and high temperature measurements (50°C~150°C) because their low resistance changes significantly in the high temperature zone and they have a fast response speed, making them suitable for overheating protection. In addition, they are easy to match with 5kΩ or 10kΩ voltage divider resistors, suitable for high-precision ADC circuits, and reduce noise interference. Typical applications include industrial equipment temperature detection and high-temperature segment monitoring of electric vehicle batteries.
• 20kΩ~50kΩ: NTC temperature sensors with 20kΩ~50kΩ are suitable for a wide temperature range (-30°C~100°C), such as automotive air conditioning systems, smart home temperature and humidity sensors, and medical equipment. This type of resistance strikes a balance between sensitivity and power consumption, and is suitable for battery-powered wireless sensor nodes.
• 100kΩ: 100kΩ NTC temperature sensors are designed for low temperature measurements (-50°C~50°C), such as cold chain logistics, freezer monitoring or polar equipment. Its high resistance value changes significantly in the low temperature range, improving detection resolution while reducing current consumption, making it suitable for IoT devices powered by button batteries.
