Water Flow Switch | Magnetic Reed Sensor G1/2 Male Thread

This G1/2 male thread water flow sensor uses a magnetic reed switch to tell if liquid is moving. It's a simple on/off switch. It closes a circuit when flow starts and opens it when flow stops. This is good for turning on other devices in a system. Features and Benefits - Magnetic reed switch works - A simple, dependable part with a magnet that moves with the water to turn on the switch, confirming flow. - G1/2 male threading - Screws right into standard half-inch female fittings. No need for extra adapters. It's good for common plumbing setups. - Low turn-on pressure - The switch activates with a starting flow pressure under 0.03 MPa. So it works well in systems with low pressure. - Wide voltage range - Runs on DC power from 5V to 220V. This means it works with small home automation projects and larger appliances. Applications - Water heater control - Acts as a flow sensor for a water heater. It makes sure the heater only runs when water is actively moving through it. - Home automation systems - Connect it with an Arduino or other controller. It can trigger alerts or actions when a tap is on or a leak is found. - Pump protection - Connect the liquid flow sensor switch to a pump's control circuit. It will automatically shut off the pump if the water supply runs dry, stopping damage. What It Is This product is a Reed Switch, functioning as a Water Flow Sensor. It is specifically a YF-C01 model with a G1/2 Male Thread. As a type of proximity sensor, it detects the presence or absence of water flow through a pipe. The sensor type is magnetic reed switch, meaning it uses a magnetic field to operate an electrical switch. Proximity sensors generally work by detecting objects without physical contact, and in this case, the magnetic reed switch detects the movement of a magnet within the flow path. Key Uses & Applications This Water Flow Sensor is suitable for applications requiring the detection of liquid movement. Its G1/2 Male Thread makes it compatible with standard plumbing connections for easy integration into existing systems. As an electronics module, it can be incorporated into various control circuits for automation. For example, it could be used in domestic water systems to monitor usage, in industrial sensor setups to confirm liquid transfer, or in irrigation systems to ensure water delivery. How to Choose When selecting a flow sensor, consider the required thread size; this specific model features a G1/2 Male Thread. Ensure the product type, a flow sensor, and sensor type, a magnetic reed switch, meet your application needs. If you need to test a proximity sensor like this, you would typically check for continuity across the reed switch terminals when water flows, and then an open circuit when there is no flow. For different applications, you might also consider other proximity sensors such as optical sensors or those with different detection ranges, for example, 5 cm.
