The ZJ-S201 liquid flow sensor is used for precise water flow measurement in the range of 1 - 30 l/min. It uses a Hall sensor and generates a pulse signal. Powered by 3.5 - 24V, it features a standard 1/2 inch thread and withstands pressure up to 1.75 MPa. It is ideal for projects with Arduino, ESP32, or Raspberry Pi. It is used in irrigation systems, liquid dispensers, and water consumption monitoring systems.

A set of two 1mm-thick test probes designed for precise measurements of SMD components. Equipped with a standard 2mm socket compatible with multimeter leads. They allow for safe operation with voltages up to 600V and currents up to 10A. Ideal for diagnostics in tight connectors, hard-to-reach sockets, and for testing sensors in electronics and auto repair shops. The set includes two pieces in red and black.

A black alligator-style test clip with soft silicone insulation is widely used in electronics, diagnostics, and prototyping with Arduino, Raspberry Pi, or ESP32 modules. Dimensions of 35 mm and a jaw opening of 12.5 mm with a strong spring ensure a stable connection. The flexible cover protects against short circuits, and the wire is attached by soldering. The component works well for creating temporary connections, extending multimeter leads, and powering test circuits.

Soldering tip cleaning sponge is an essential accessory in an electronics workshop. Its initial dimensions are 50 x 35 x 2 mm, and after mandatory wetting in water it expands to 57 x 37 x 5 mm. The compact size fits most soldering stations. Regular use enables quick removal of contaminants and significantly extends tip life. The product works well for routine equipment maintenance in professional service shops and amateur repairs.
