AJMRTC 5Pcs NTC Thermistor Temperature Sensor Probes, 100K 1% Tolerance B3950 Waterproof NTC Temperature Sensors, High Precision Metal Probe for 3D Printer, Boiler, HVAC, DIY Temperature Control Proje

AJMRTC waterproof NTC thermistor set includes five 100K high-precision temperature sensing probes with B3950 B-value and 1% accuracy. The thermistor core is sealed inside a small metal head with waterproof encapsulation, which protects the internal sensing chip from condensation, splashing water and humid air. It changes resistance predictably with temperature, and you can read the value through a voltage divider circuit paired with Arduino, STM32, dedicated thermostat boards and other MCUs. The B3950 characteristic parameter is widely supported by open-source firmware such as Marlin for 3D printers. The soft cable is easy to route inside equipment enclosures, and the tinned terminals help speed up wiring during assembly. These sensors are commonly selected for 3D printer hotend and bed temperature detection, water heaters, boilers, incubators and industrial temperature feedback systems. This is a passive resistive sensor; it requires a sampling circuit and corresponding parameter configuration on your controller. Please verify your controller firmware is configured for 100K B3950 before installation.
