The US-100 is very similar to the popular HC-SR04 ultrasonic sensors, and even looks the same, but has a few extra tricks This sensor can run from 3-5V so you don’t need any logic level shifters or dividers. Just power from whatever your microcontroller provides You can use in “HC-SR04” mode or in “Serial UART” mode. This US-015 ultrasonic module can realize 2 ~ 700cm of non-contact ranging function, has 5 V of wide voltage input range, static power consumption is less than 3mA. Their own temperature sensor will revise the ranging and has many communication modes like GPIO, just like watchdog inside, very stable and reliable.
Sep 18, 2017 · Ultrasonic Sensor Pin Configuration. Trigger pin is an Input pin. This pin has to be kept high for 10us to initialize measurement by sending US wave. Echo pin is an Output pin. This pin goes high for a period of time which will be equal to the time taken for the US wave to return back to the sensor. Banner’s T30UX ultrasonic sensor is the perfect sensor for detecting clear material for loop control because it uses sound rather than light, which makes it more accurate and cost-effective for this specific application. Although the material is clear, it presents a solid surface for an ultrasonic sensor to bounce a sound wave.
