Temperature Sensor | 10K Waterproof Probe | 1m-5m Cable for W1209

This NTC thermistor temperature sensor gives you exact temperature readings for your electronics projects. It has a 10K resistance, a 1% tolerance, and a B-value of 3950. The stainless steel probe is waterproof, so you can use it to measure liquid temperatures or outside. Features and Benefits - Waterproof stainless steel probe - You can safely put the sensor in liquids to check their temperature, like in aquariums or water-cooling systems. - 10K resistance with 1% tolerance - This gives you steady and exact temperature readings. That's good for things like 3D printer hot ends or HVAC systems. - Comes with an XH2.54 connector - It plugs right into many microcontrollers and temperature controllers, such as the W1209. You can start using it fast. - Works from -20°C to 105°C - It measures a wide range of temperatures. This is helpful for both cooling and heating uses. Applications - DIY electronics and Arduino projects - People often pick this NTC sensor for Arduino to watch the environment or run fans and heaters. - HVAC and appliance repair - Use this wired NTC sensor to check or replace bad probes in air conditioners, fridges, or water heaters. - 3D printer upkeep - It works as an accurate NTC thermistor sensor for the hot end or heated bed. This helps keep printing temperatures steady. How It Works This NTC Thermistor Temperature Sensor operates by changing its electrical resistance in response to temperature fluctuations. As the temperature around the waterproof probe changes, the 10K Ohm resistance of the sensor alters accordingly. This variation in resistance is then read by a compatible controller, such as the W1209 or W1401. The controller interprets these resistance changes to accurately determine the current temperature, allowing for precise monitoring and control within various systems. The X5.24-2P connector ensures a secure and reliable connection to the control unit. What It Controls This temperature sensor is designed to provide accurate temperature readings to compatible controllers like the W1209 and W1401. It acts as a crucial input for these control units, enabling them to regulate temperature-dependent systems. For instance, a water temperature sensor of this type can be used to monitor the temperature of liquids, allowing a controller to activate or deactivate heating or cooling elements to maintain a desired temperature range. Its waterproof design makes it suitable for use in environments where moisture is present, expanding its application possibilities. Signs of a Failing Sensor A failing temperature sensor may exhibit several indicators. If the compatible controller, such as a W1209, displays inaccurate or wildly fluctuating temperature readings, this could suggest an issue with the 10K Ohm NTC thermistor. Another sign is if the system it controls, for example, a heating element, is not maintaining the set temperature correctly, despite the controller appearing to function. Intermittent readings or a complete lack of temperature display from the sensor are also strong indicators of a fault. The waterproof probe should be inspected for any visible damage. Location This 10K waterproof probe with a 1m, 2m, 3m, or 5m cable is designed for versatile placement. Its waterproof feature allows it to be submerged or placed in damp environments to measure liquid or ambient temperatures. The length of the cable provides flexibility in positioning the sensor away from the main control unit, such as a W1209. For accurate readings, the sensor should be placed directly in the environment or medium whose temperature needs to be monitored. Ensure the X5.24-2P connector is securely attached to the compatible controller and protected from physical stress. Common Symptoms of a Bad IAT Sensor While this product is a general NTC Thermistor Temperature Sensor and not specifically an Intake Air Temperature (IAT) sensor, a faulty control sensor in an air intake system would typically lead to incorrect air temperature readings being sent to the engine management system. This could result in symptoms such as poor fuel economy due to the engine receiving an incorrect fuel-air mixture, rough idling, or a reduction in engine power. An intake air temperature sensor is located in the engine's air intake tract, usually after the air filter and before the throttle body, to measure the temperature of the incoming air.
