Many electronic devices operate in conditions where the fan rotates at idle, and create a constant, annoying noise, accelerating the wear of the fans. The function of this thermocontroller is to reduce the noise from the constantly-running fans by stopping them until the temperature exceeds a predetermined threshold. The module can be used in computer system units, in power units, and any other electronic devices that use cooling with fans. The proposed thermal controller works with 12V or 24V fans, in the start-stop mode, with a hysteresis of 2-5 ° C.

The M158.3 metal detector is a device similar to hand-held metal detectors used by guards to search for metal objects in people’s clothing. The device is able to find metal objects from ferrous and non-ferrous metal at a short distance. Using this metal detector, you can detect keys, a mobile phone that are under clothing, a metal profile under drywall. For gaming purposes, young people can look for coins hidden under a carpet or in the sand.
Included is a soldered module and a compartment for two AAA finger batteries with a switch.
Batteries are not included. You only need to solder the two wires to the metal detector board and, if desired, fix the battery compartment to the board with double-sided tape

Designed for creating LED lamps using LED strips or rulers and aluminum profiles. The sensor is mounted directly into the profile. The principle of operation of the sensors is based on the reflection of the infrared (IR) rays emitted by them from nearby objects at a distance of up to 5 or 10 cm. Thus, waving a hand or opening and closing a cabinet door triggers the sensor.
