{"title":"Octopus Mercury Sensor","handle":"octopus-mercury-sensor","url":"/products/octopus-mercury-sensor","description":"The Octopus Mercury Sensor is a tilt and angle detection module based on the mercury switch principle. When tilted, the mercury inside the switch makes or breaks contact, providing a simple way to detect orientation changes and object levelling.\n\nPart of the Octopus Electronic Bricks range from ElecFreaks, this module features a 3-pin interface for easy breadboard-less connection to Arduino and compatible boards.\n\nKey Features\n\n\nMercury Switch Principle – Reliable tilt and angle detection using liquid mercury contact\n\nHigh Sensitivity – Fast response to orientation changes\n\nSimple Interface – 3-pin connector (Signal, VCC, GND) for plug-and-play use\n\nAnalogue Output – Connects to any analogue input pin\n\nLong Life – Stable operation with durable mercury switch element\n\n\nSpecifications\n\n\nOperating Voltage – 5 V\n\nInterface Type – Analogue\n\nPin Definition – 1: Signal, 2: VCC, 3: GND\n\n\nIdeal For\n\nTilt detection and orientation sensing\nObject levelling applications\nAngle measurement projects\nArduino and microcontroller prototyping\n\n\n\nWarning: This module contains mercury. Handle with care and dispose of responsibly according to local regulations. Do not break open the sensor element.\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4582,"title":"Default Title","sku":"EF-EF04006","price":7.09,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
