Ultrasonic sensor
This module is used to measure distances by using ultrasonic sounds.
The Arduino MCU sends a short pulse to trigger the detection, then listens for a pulse on the same pin using the pulseIn() function.
Using the speed of sound, this time can be converted to distance:
Distance = High level time * sound velocity (343.2m/s) / 2.
● Detection distance: 2cm-450cm.
● Accuracy: Up to 0.3cm.
● Input trigger signal: 10us TTL impulse.
● Echo signal : output TTL PWL signal.
● Accuracy: Up to 0.3cm.
● Input trigger signal: 10us TTL impulse.
● Echo signal : output TTL PWL signal.
● Digital I/O: 2 (Trigger, Echo-R)

Water sensor
This is a simple water sensor, it can be used to detect soil moisture. Module output is high level when the soil moisture deficit, or output is low. It can be used in module plant water device.
● Operating voltage:3.3V~5V
● Dual output mode,analog output more accurate
● Panel PCB Dimension: 30mm * 16mm
● Soil Probe Dimension:60mm*30mm
● With power indicator (red) and digital switching output indicator (green)
● Having LM393 comparator chip, stable
