Module with a gas concentration sensor MQ2, which enables the detection of LPG, butane, propane, methane, alcohol, hydrogen and smoke. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020055

Module with 6 QTR type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 40 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4146

Capacitive liquid level sensor for mounting on non-metallic pipes. DFRobot SEN0509

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features a high-sensitivity analog VOUT output with a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5455
