This wave scanner enables you to receive powerful radio waves generated, for example, as interference radiation from devices and some modern (LED) lights. But it can also be radio waves from a real radio station. This electrosmog detector is 100 mm long and should be soldered together. This battery-powered kit enables you to build an electrosmog detector. Electrosmog is the interference radiation emitted by many devices. Ideal for STEM and STEAM teaching. Using this kit, children and adults can learn how to read a construction drawing and to build a detailed model. 100 mm long, construction time approx. 35 minutes, 19 components Supply voltage 1.5 V, maximum current consumption around 30 mA. https://elecena.pl/product/18591155/arx-rws-electrosmog-detector 2021-05-27 https://elecena.pl/product/18591155/arx-rws-electrosmog-detector 2022-05-15
