Review: Surprisingly easy to use. - I was surprised at how effective these are and how easy they are to use with an Raspberry Pi Pico 2 W. I made a 3D printed cone to fit into a netcup space for hydroponics. When the water drops below the bottom of the netcup level the sensor triggers from wet to dry. Here is the CircuitPython code: # Minimum FS-IR02B Water Level Sensor Code import board import digitalio import time print("=== WATER LEVEL SENSOR - MINIMUM CODE ===") # Setup water level sensor on GP6 water_sensor = digitalio.DigitalInOut(board.GP6) water_sensor.direction = digitalio.Direction.INPUT water_sensor.pull = digitalio.Pull.UP print("Water level sensor ready on GP6") print("Hardware connections:") print("- VCC: Connect to 3V3 (Pin 36)") print("- GND: Connect to GND (Pin 38)") print("- Signal: Connect to GP6 (Pin 9)") print("") try: while True: # Read sensor (True = water present, False = no water) water_present = not water_sensor.value # Inverted logic if water_present: print("Water detected!") else: print("No water detected") time.sleep(1) # Check every second except KeyboardInterrupt: print("Stopped") except Exception as e: print("Error: " + str(e))
Review: OUTSTANDING VALUE - Very fast shipping !! And for someone living in teh arctic that's says a lot. The sensor worked very well, it is made of quality materials and is astonishingly easy to use. The kit comes with three sensors but the board only takes one of the sensors due to the connector types mounted on the board. Now, it does come with extra connectors that will fit the sensors, so I am going to see if I can modify the board to solder in the extra connectors included with the kit. I'm thinking that this board is used for many other types of sensors which have different types of connctors and the company includes the extras for setting the board up for three inputs. I am very happy with the product and plan to purchase more. Photos from left to right. Photo one no water board set. Photo two the sensore. Photo three the red LED is le=it indicating the sensore is in the water.

### ⭐⭐⭐⭐⭐ Waterproof water level sensor
*by J***H on November 28, 2023*

The sensor is sealed, you don't have to worry about drilling a tank or bucket if you don't want to. You can just hot glue it on the inside of a bucket or water tank if that is what you want to do and it will be fine. *You must be certain that the type of liquid will not damage the sensor. This sensor is plastic and is NOT for solvents like gasoline or acetone!* This light based water level sensor works great. I just tried it in R/O water and it works as expected. The quality of what I've got here looks good. I am not sure what the board is supposed to be for, perhaps this also makes it a replacement for something else. On Arduino, you can just digitalRead the sensor for a HIGH or LOW value with no board or other components involved. Seems to be highly responsive to its state change. Trivial to code and implement. A great product! *For higher accuracy, use AnalogRead on the sensor (which is 5v) to get a value from around 25-1050. They read very low, under 200 or usually less when wet in R/O water and usually over 1000 out of water. I use 500 as my threshold and it works great.
