With hydroponic cultivation we mean a different method of plant growth, in fact instead of the earth there is water with dissolved mineral salts that flows between the roots. In this project we will see how a hydroponic greenhouse controlled by an ESP8266 was built. The system consists of pumps and temperature sensors controlled by…
Nixie valve display watches will have their vintage appeal but we know how delicate they are due to the glass and the high voltage needed to make them turn on. This project makes the Nixie watches more resistant, with a more modern look thanks to the RGB LEDs used to display the digits and which…
This is the first generation of my Arduino based mini-weather station with Wi-Fi connection, which is able to post data publicly online using the ThingSpeak platform. The weather station collects the following data related to the weather and environment using different sensors: Temperature Humidity Atmospheric pressure Light intensity UV index Dust concentration The aim is…
The Seeed Studio Grove Base Kit for Raspberry Pi is a beginners kit for beginners to get started with the Raspberry Pi in a fun and easy way. It has 10 Grove sensors instead of 12 on Seeed’s GrovePi+ Starter Kit, but it also adds three sensors: Mini PIR motion sensor, moisture sensor, and servo….
Hackster.io members Damir Mukametkarim and Artem Savchuk have created a great tutorial on building a Raspberry Pi plant monitoring system, harnessing the features of Azure IoT and Node.js. As you can see from the image above, the core of the system is the Azure Internet of Things hub which allows transferring telemetry from sensors to…
“The clock actually consists of two clocks, the first being a 6 x IN-18 tube clock which is mounted on the clock’s top and displays both time and date. The second clock, this time based on 6 x IN-12A and 2 x IN-15A nixie tubes displays at the front of the clock and can display,…
Aptly named TWIST the open source environmental monitoring system is capable of sending tweets and collecting meteorological data thanks to its include gas, rain, light, temperature and humidity sensors. “Meet Tweeting Weather IoT Station aka TWIST – a DIY, Open-Source Environmental Monitoring and Meteorological Data Acquisition Platform. The purpose of TWIST is so that individuals…
Anavi Technology has this month launched a new product via the Crowd Supply in the form of the ANAVI Thermometer, an ESP8266-powered, open source, wireless dev board equipped with temperature and humidity sensors, so it can act as a thermostat for home automation. The Anavi Thermometer Development board is fully compatible with the Arduino IDE,…
UK-based distributor RS Components announced the availability of San Francisco based UrsaLeo’s UrsaLeo Pi IoT development kit. UrsaLeo’s kit, which was recently introduced by Mouser under its original UrsaLeo UL-RPI1S2R2 name, is designed to send sensor input to Google Cloud for storage and analytics. The kit is designed for Industry 4.0, automotive diagnostics, healthcare, and…
Designed to provide plenty of feedback on your plants environment, soil and condition, the Raspberry Pi plant monitoring system is also capable of automatic watering when required and updating you when anything may need your attention. Smart Garden System (or SGS for short) is an introductory, easy to build Raspberry Pi based environmental monitoring and…
OpenMinder is an open-source DIY project from Autogrow targeted to technology developers and for application with small growers. Released under a Creative Commons BY-NC-SA license, OpenMinder provides an open-source API used in conjunction with a Raspberry Pi HAT. OpenMinder™ is a product that you can build yourself, but more than that it represents where this…
Rak Wireless has recently launched a new products called RAK8211-NB iTracker based on a Quectel BC95-G NB-IoT module, Nordic Semi nRF52832 Bluetooth 5 chip, and Quectel L70-R GNSS module. The asset tracker module also comes with 5 different sensors to monitor motion and environmental data, and can optionally be powered directly by a solar panel….
