Liquid Level Sensor Non-Contact | 12V DC Stick-On Switch

The XKC Y25 T12V is a liquid level sensor. It sticks to the outside of a tank. It doesn't touch the liquid. This detector works with a voltage range from 5-24V. This makes it a flexible sensor module for many projects. It works with non-metallic containers. Features and Benefits - Wide 5-24V operating voltage - It powers directly from common sources. This includes USB power banks, Arduino boards, and industrial 24V systems. - Solid-state electronics - It has no moving parts. This means it won't wear out or get stuck like a mechanical float switch. - Simple NPN output - It gives a straightforward on/off signal. This can directly drive small relays, LEDs, or microcontroller inputs. - Easy stick-on installation - Just peel the backing. Apply it to the tank at the height you want to detect. No drilling is needed. Applications - Lab equipment - Monitor fluid levels in glass or plastic beakers. This avoids contaminating the contents. - Custom appliances - Add a low-level indicator to a coffee machine, water dispenser, or humidifier. - Educational projects - It's a simple and effective sensor. It helps teach students about capacitive sensing and automation. Mechanical Ball / Rolling-Element Switches (Simple On/Off) These are a common type of tilt sensor, operating on a simple principle. Inside the switch, a conductive ball or rolling element moves with changes in orientation. When the device tilts beyond a certain angle, the ball makes contact with two electrical terminals, completing a circuit and acting as an electrical switch. This provides a basic on/off signal, indicating whether a tilt has occurred. They are robust and reliable for applications where a simple tilt detection is sufficient, such as safety cut-offs or basic orientation sensing. MEMS Accelerometers (Precise Angle Measurement) MEMS (Micro-Electro-Mechanical Systems) accelerometers are sophisticated gravity sensors that detect acceleration in one or more axes. By measuring the acceleration due to gravity (1g), they can determine the precise angle of tilt. This allows for continuous and accurate measurement of inclination, rather than just a simple on/off state. They are highly sensitive switches, capable of detecting subtle changes in orientation and are often used in applications requiring detailed angle information or shake detection, where the product's tilt and shake can be monitored precisely. Optical Tilt Sensors Optical tilt sensors work by using light to detect changes in orientation. These sensors typically involve a light source and a light detector, with a moving element or liquid that obstructs or reflects the light path as the device tilts. When the tilt changes, the amount of light reaching the detector varies, providing a signal that indicates the degree of inclination. This method offers a non-contact detection method, which can be beneficial in environments where mechanical wear or electrical interference might be a concern for other sensor types. Quick Comparison Different tilt sensors offer varying capabilities. Simple mechanical ball switches provide a straightforward on/off signal for basic tilt detection. MEMS accelerometers, as gravity sensors, offer precise angle measurement and can detect shake, providing continuous data on inclination. Optical tilt sensors use a non-contact detection method, often relying on light to sense changes in orientation. The product described, a Non-Contact Tilt Sensor with Liquid Induction Switch and Hall Sensor theory, offers a specific combination of these characteristics, focusing on non-contact detection and a 12V DC voltage. The Gravity Sensor The term "gravity sensor" broadly refers to any sensor that detects the force of gravity, which can then be used to determine tilt or orientation. How does a tilt sensor work using gravity? By measuring the component of the Earth's gravitational pull (1g) along different axes, the sensor can calculate its angle relative to the horizontal. This is fundamental to how many tilt sensors operate. The product's Hall Sensor theory suggests it uses magnetic fields, likely influenced by a liquid or moving element, to detect changes in orientation, effectively acting as a gravity sensor for tilt detection.
