Product Description

With this kit by MitchElectronics, practice your soldering skills as you build a fully controllable Hi/Low Detector. RoHS and REACH compliant, ideal for classrooms and workshops, and superb for beginners looking to improve their soldering skills!

This kit is part of the SMD Trainer range that only uses SMD parts to test out your soldering skills. With this kit, build a Hi/Low detector that can alertĀ you when a signal is either too low or too high. Two on-board LEDs indicate whether the signal is too low or high, and two potentiometers provide fullĀ control of the high and low detection levels.

Before making this kit, be sure to read our SMD soldering guide found in our resources page, and pay extra attention when positioning componentsĀ because de-soldering SMD parts can be extremely challenging.

Applications

The Hi/Low Detector SMD Trainer is an excellent kit for testing soldering skills, especially with the potentiometers and the MMBT3904 transistor (asĀ these are very small). Regarding practical applications, this small module is great for scenarios where some control signal needs to be maintained atĀ a specific level (such as a temperature-controlled environment). The high output can be used to control devices, while the low output can be used toĀ enforce a safety system or failsafe. For example, a green house that gets too hot can use the high output to open the windows, but if theĀ temperature falls too low, then the low output can be used to engage a heater.

Notes

Note that product specifics such as output frequency depend on the tolerance of the components. The numbers provided here are an approximation only.

All parts sold by MitchElectronics are compliant with RoHS and REACH directives which ensure that they can be used in commercial environments as well as complying with environmental laws.
