Watchible NB-IOT board
Douma Nov 09,2022
Watchible is an NB-IOT add-on board for the Raspberry Pi Pico. It is low cost, and low power. It is meant to monitor any trigger with a low impedance interface. Both the Pico and the Quectel BCC-66 modem can be put to sleep for up to 12 hours, and will wake up if an alarm is triggered. This reduces power consumption and allows Watchible to be in remote locations, powered by a simple battery for months or years, depending on how big the battery is and how many times it has tow wake up to insure a...

Life happens. IVYPOTS takes cares of the plants while you are away
Khouatra Nov 05,2022
 //Project under developpement.// IntroductionIvypots is a solution for people who want to grow indoors vegetables, without worrying about How Often & How Much Watering the Houseplants are. Ivypots uses the Peltier Effect to generate water from the humidity to finally be able to water the plants. Thanks to the SD Card we can use the results to create a graph in Excel to analyze the plants to determine how much and how often the plants need to be watered to give the best possib...

ESP8266 Remote Relay
Reboot Oct 23,2022
This pcb has a WeMOS D1 Mini with ESP8266 to control the on board relay.Control of the relay can occur wirelessly, and the ESP8266 UART pins are also available on a header to optionally allow an external RS485 or bluetooth module to be used.The Github project uses ESP-NOW to communicate between this relay control board and another ESP8266 board that uses a current transformer: https://www.pcbway.com/project/shareproject/SCT013_Current_Monitor_for_ESP8266_cc7ccd2e.htmlWhen the current transformer...

Picoclick C3 - most advanced IOT-Button
König Oct 21,2022
The Picoclick is a tiny device which can be used as an IOT-Button. It is a one-button-device which let's you control different stuff in your smart home or the internet of things. A basic example is to toggle a light bulb by a button press. Moreover the Picoclick-C3 can be used as a mini development board, because it comes with an FPC extension port where other hardware can be connected to - even I2C is possible.The Picoclick is an ultra low power device, it only consumes 2μA of current in idle s...

ESP32 IoT Relay Control
ELECTRONOOBS Oct 20,2022
This PCB here that I call NOOBIX gives you full IOT control for anything. A lamp, a fan, your stereo speakers, your printer, anything you want. With a simple online push of a button from anywhere in the world, you can turn ON or OFF any device that works at 220V AC. This project is based on a previous tutorial where I show you how to use the ESP32 and the HTTP library in Arduino IDE. The PCB has its own voltage regulator from 220V AC to 12V, 5V and 3.3V DC, it has a solid state relay to control ...

How to make RMS to DC Converter using IC AD736
electronicguru0007 Oct 17,2022
A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results.The IC AD736 has few functional subsections like the input amplifier, full-wave rectifier (FWR), RMS core, output amplifier, and bias section. The Input amplifier is constructed with MOSFETs, so it is responsible for the high impedance of this IC.After the input am...
