Description: 1. The SEN-HZ21WA is a 1/2 inch water flow sensor designed for measuring and monitoring the volume of water flowing through it. 2. Sensing Technology: This sensor utilizes ultrasonic technology, which emits sound waves to measure the distance between the sensor and the water surface, enabling real-time water flow rate measurement. 3. Accuracy: With a measuring accuracy of up to ±3% of full scale for water flow rates, this sensor offers high precision and reliability in various applications. 4. Compatibility: This versatile sensor can be connected to Arduino boards and other microcontrollers using standard analog input pins. It also supports various communication protocols such as I2C, UART, and CAN bus for easy integration with IoT systems. 5. Waterproof Design: The SEN-HZ21WA is built with a waterproof casing that protects the sensor against moisture, ensuring its longevity when used in aquatic environments. 6. Adjustable Zero Point: Users can easily calibrate and adjust the zer
