Float Switch Sensor

The Float Switch Sensor is a simple and reliable liquid level detection device designed to detect the presence or absence of water and other compatible liquids. It works using a floating mechanism that moves with the liquid level and activates an internal switch when the preset level is reached. This sensor is widely used for automatic water level control, tank monitoring, pump automation, and industrial liquid management systems. Available at Directronics, the Float Switch Sensor is ideal for students, hobbyists, makers, educators, and professional engineers working on automation and IoT-based monitoring projects.
