{"title":"Octopus Water level sensor","handle":"octopus-water-level-sensor","url":"/products/octopus-water-level-sensor","description":"The Octopus Water Level Sensor detects water level using exposed parallel traces on the PCB. As the water level rises, more traces are submerged, producing a higher analogue signal output. Compatible with micro:bit (3 V) and other microcontrollers operating at 3–5.5 V.\n\nPart of the ElecFreaks Octopus series, this sensor uses the standard 3-pin connector (GND, VCC, Signal) for easy plug-and-play connection with Octopus:bit and similar breakout boards.\n\n\nWarning: The components above the MAX water level line are not waterproof. Do not submerge the sensor beyond the marked line.\n\n\nKey Features\n\n\nAnalogue Output – Signal proportional to water level for easy threshold detection\n\n3-Pin Connection – GND, VCC, Signal for simple wiring\n\nmicro:bit Compatible – Works at 3 V; read analogue values via MakeCode\n\nCompact – 59.15 × 19 mm, 5.5 g\n\n\nSpecifications\n\n\nWorking Voltage: 3–5.5 V DC\n\nConnection: G (GND), V (VCC), S (Signal)\n\nDimensions: 59.15 × 19 mm\n\nWeight: 5.5 g\n\n\nIdeal For\n\nWater level monitoring and alarms\nmicro:bit science projects\nSimple liquid level detection\n\n\nResources\n\nMakeCode Example Program\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4628,"title":"Default Title","sku":"EF-EF04094","price":2.43,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
