Operating voltage: 3.3V~5V.
Adjustable sensitivity (shown in blue digital potentiometer adjustment)
Dual output mode,analog output more accurate.
A fixed bolt hole for easy installation.
With power indicator (red) and digital switching output indicator (green).
Having LM393 comparator chip, stable.
Water Level Sensor Depth of Detection Sensor for ArduinoOperating voltage: DC3-5V
Operating current: less than 20mA
Sensor Type: Analog
Detection Area: 40mmx16mm
Operating temperature: 10℃-30℃
Humidity: 10% -90% non-condensing
(1) Using IO trigger for at least 10us high level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level , time of high output IO duration is
the time from sending ultrasonic to returning.
Test distance = (high level time×velocity of sound (340M/S) / 2
