Filter for sensor (use Item no. KR04314 and KR04571)
It’s recommended to use Ultrasonic filter if you have unstable ultrasonic reading during reading the sensor. The power supply filter kits includes a 10ohm resistor, a 100ohm resistor, and a 100uF capacitor. The power supply filter is recommended for environments with unclean power or electrical noise. Electrical noise may cause unstable reading ranges. The power supply filter helps clean unstable or dirty power supplies that may cause a sensor to have unstable range reports.
