SKU: EF-EF04029

An analogue gas sensor module based on the MQ-2 sensor, part of the Octopus Electronic Bricks series for plug-and-play integration with Arduino and compatible boards. Detects a wide range of combustible gases and smoke with high sensitivity and fast response time. Detectable Gases LPG, i-butane...

SKU: EF-EF04011

The Octopus Touch PAD Sensor is a capacitive touch module based on the TTP223-BA6 IC. It detects touch through dielectric materials such as glass, ceramic, and plastic, making it suitable for touch-through-panel applications. The module connects via a 3-pin Octopus connector for plug-and-play use...

SKU: EF-EF04060

The Octopus MQ3 Alcohol Sensor Brick from ElecFreaks is an analogue gas sensor module with high sensitivity to alcohol vapour. It outputs an analogue voltage proportional to the detected alcohol concentration, making it straightforward to interface with Arduino and other microcontrollers. The MQ...

SKU: LB-TILT

A simple tilt sensor module that detects orientation changes. When tilted, the internal conductive ball breaks the circuit; when returned upright, it reconnects — providing a digital output signal. It's a compact, low-power way to add basic tilt detection to your projects. The module outputs a d...

SKU: EF-EF10030

A passive infrared (PIR) motion sensor module based on the BISS0001 IC, capable of detecting human movement at up to 7 metres. Outputs a digital high signal when motion is detected, making it easy to interface with Arduino, Raspberry Pi, and other microcontrollers. Features adjustable sensitivit...

SKU: EF-EF03085

The HC-SR04 is a widely used ultrasonic distance sensor that provides non-contact measurement from 2 cm to 450 cm with up to 3 mm resolution. It uses a 40 kHz ultrasonic transducer pair — one transmitter and one receiver — to calculate distance based on the time-of-flight of a sound pulse. With ...
