Portable instrument that allows you to check the condition of the telephone line by means of multi-colored LED signaling. The signaling identifies the line voltage, polarity or any interruption. Double socket with RJ11 plug and RJ11 jack
A set of tools that – for an affordable price and without difficulties – is capable of identifying and verifying the features of BJTs, FETs, thyristors, diodes, etc. Until a few years ago, it would have been a utopia to have a very small, portable, relatively cheap and universal tool for the…
ESP32 Low Power Module, based on Espressif’s SoC capable of providing full compatibility with the standard MINI ESP32 version. Compared to the latter, this module lacks a USB interface, dedicated exclusively to programming the ESP32, making it ideal for low-power applications. Compatible with the Arduino IDE, it includes a WiFi 802.11 b/g/n transceiver and a…

The Xbee Shield allows an Arduino board to communicate wirelessly using Zigbee. It can be used as a serial / USB substitute or you can put it in command mode and configure it to adapt it to a wide variety of transmission networks. It also has male / female connectors to use the digital pins…
This monitoring device is useful for keeping track of the liquid level (such as water) inside tanks, reservoirs, and containers. It features seven inputs (to connect electrodes) that can be positioned inside the tank. Each electrode is associated with a corresponding LED that lights up when the liquid reaches the desired level (i.e., the electrode)….
