The XH-M203 Automatic Water Level Controller Module provides a smart and reliable solution for automated water management in domestic, agricultural, and industrial applications. Designed to monitor and control water levels without manual supervision, this module automatically turns the pump ON when the water level is low and OFF when it reaches the preset upper limit, maintaining optimal water balance in tanks or reservoirs. Equipped with a high-power 10A relay, it can control a wide range of pumps, solenoid valves, or external devices. The dual-probe sensing system ensures accurate water level detection, while LED indicators provide visual feedback for power and operational status. Supporting a wide operating voltage of 12V to 40V (AC/DC), it’s easy to install and highly versatile. The XH-M203 module is ideal for water storage automation, irrigation systems, and industrial liquid level control setups, offering efficient and maintenance-free operation. Featured By RoboticsBD.
