AJMRTC waterproof NTC thermistor set contains six temperature sensing probes, mixing 5K and 10K versions with B3950 B-value and 1% high precision tolerance. The sensing core is sealed inside a compact metal probe with waterproof encapsulation, protecting the thermistor core from moisture, water splash and condensation. It outputs variable resistance according to ambient temperature, which can be read by MCU analog ports after simple voltage divider circuit design. The B3950 characteristic ensures consistent temperature-resistance calculation, easy for developers to configure software conversion formulas. These probes come with flexible insulated wires and pre-tinned ends for quick wiring. They are commonly used in air conditioners, refrigerators, water heaters, incubators and custom temperature alarm systems. Please note that this sensor measures temperature by resistance change and needs external sampling circuit and program calibration. Confirm you select the correct resistance value (5K or 10K) matching your controller before installation.
