Thanks to ESP8266, the cost of WiFi relays has dramatically come down, but so far, I could not find an all-in-one solution with ESP8266, relay, AC power and enclosure, and for example I’m still using NodeMCU board, a relay board, a USB power supply, and put all that into a plastic jar in order to control a water pump. It works but it’s not ideal, and solutions like Wemos D1 mini with relay shield improves things further, but Electrodragon has come with a connect-and-play WiFi IoT relay that integrates everything including the case for $6 + shipping. Wifi IoT Relay Board Based on ESP8266: WiFi module – ESP-12F based on Espressif ESP8266EX WiSoC Relays – 2x Songle SRD-05VDC-SL-C relays supporting 125VAC/10A, 250VAC/10A, 30VDC/10A, 28VDC/10A Input/Output – 3x terminal blocks for relay and power Expansion – 12-pin header with Rx/Tx, GPIO4, Btn2, GPIO15, 5V/GND, ADC, GPIO5, Btn1, OUTPUT1, and 3V3 Debugging […]
The European Version of Orvibo Wiwo S20 Smart Socket Has Been Found to Pose a “Serious Risk”
Orvibo Wiwo S20 is a WiFi smart socket that can be controlled by a smartphone and some people are using it with OpenHAB open source automation software. The socket has four versions with with US, UK, EU or AU plug types, and some of my clever readers mentioned that the European plug was mot likely NOT compliant with European regulations, was likely dangerous, and should be limited to 2.5A instead of 10A. It turns out they were right, as the European commission issued a safety notice last declaring Orvibo Wiwo S20 to be dangerous with risk of electric shock. The document further explains: The shape of the socket is not correct: when a plug is inserted the live pins of the plug are accessible. Appliances which should be earthed can be connected to the socket but the socket itself is not earthed. The product does not comply with the requirements […]
Tibbo Project System is a Modular Linux IoT Prototyping Platform based on TI Sitara Cortex A8 Processor
If you’ve found yourself needing to quickly demo a system that does not look like a mess of wire to a customer, or your project is requires low production volumes, making the cost of designing your own and mass-producing the hardware prohibitive, Tibbo Project System might be worth looking into. It features an almost bare board powered by Texas Instruments Sitara processor, and a large area for Tibbit blocks to add features as needed, as well as an enclosure. Size 3 Linux Project PCB (LTPP3) specifications: SoC – Texas Instruments Sitara AM335x Cortex A8 processor up to 1.0 GHz System Memory – 512 MB DDR3 Storage – 512 MB NAND flash, 2KB EEPROM, optional micro SD slot Connectivity – 10/100M Ethernet (RJ45), optional WiFi (via LW1000 module) and GPRS connectivity (via Tibbit #47) Expansion – 51 I/Os: 7x tiles 14x sockets for Tibbit module including 4x with UART capability up […]
RTU-5025 GSM Relay Controller Supports Up to 64 Phone Numbers
We’ve already seem boxed WiFi and Bluetooth wireless relays that can be used to turn on and off appliances using a smartphones or web applications, but I’ve just been made aware that GSM relay controllers such as RTU 5025 could also be a good options since they allow for authentication using the mobile number, can be used with any phone, not only smartphones, and don’t cost anything to operate, beside the eventual maintenance cost of the SIM card inside the device, since the relay does not actually answer calls. It can also send an SMS to the owner each time the relay is activated, in which case the cost of SMS might have to be considered. RTU 5025 specifications and key features: Connectivity – GSM PHASE 2/2+@ 850/900/1800/1900 MHz with SIM card slot + GSM antenna Output Relay – 3A/240V Rated Voltage – 12V/1A Working Temperature – -10 to 60 […]
Getting Started with Wemos D1 mini ESP8266 Board, DHT & Relay Shields
Wemos D1 mini is an ESP8266 board that’s interesting thanks to its size, its low price ($4), micro USB power, its shields, and a documentation that looks fairly good. The board can be programmed with Arduino or Lua, and supports both serial and OTA programming. I’ve decided to give it a try and bought the board together with two temperature shields, a relay shield, and micro SD shield. I got all for $ 14.00 from Wemos Aliexpress shop, and it took about one month for delivery. I can also see they’ve recently released a new OLED shield selling for about $5. All shields were shipped inside their own anti-static bags. The pins are clearly marked on both side of the board and the shields. One side of the board features ESP8266 module. and the other side has CH340 serial to USB chip, and the reset button. The provided headers make […]
$100 Chuwi Ilife V5S Autonomous Robotic Vacuum Cleaner Offers an Alternative to iRobot Roomba
iRobot Roomba autonomous vacuum cleaners have been around since 2002, with the robots automatically cleaning the floor, detecting walls and edges, going around table and chair feet, etc… The company also produced iCreate 2 programmable robot for educators, students and developers who wants to learn about robotics, and works with Arduino and Raspberry Pi boards. I had seen similar cleaners from Chinese vendors in the past, with prices starting at $30, but they looked basically useless based on the specs, but yesterday I discovered Chuwi Ilife V5S robotic vacuum cleaner and mop that seems pretty decent, and even can go back to its charging station automatically. Chuwi Ilife V5S key features and specifications: Anti-collision System, drop avoidance induction 50db low noise design; 850pa strong suction Sensors – 10 IR sensor on sides and bottom, OBS (Optical backscatter point sensor) sensors, 1 set wall sensor. (Note: OBS is based on IR, […]
TinySine Bluetooth, WiFi and USB Relays Come with an Optional Enclosure, Support Android and iOS Smartphones
It’s now fairly easy to find the hardware to create WiFi or Bluetooth controlled relays, but you usually have to design your own enclosure and Android app, and if you’d like something that’s ready to use out of the box TinySine wireless relays such as TSRB430 (Bluetooth) or TSRW430 (WiFi) might be an interesting option. There;s also a version with USB control. TSRB430 / TSRB430 / TSRU430 specifications: 4x Omron G8P 30A/250VAC | 20A/28VDC relay; SPST-NO (normally open) types. Connectivity – XBEE module either: Bluetooth Bee module based on CSR BC417143 Bluetooth 2.0 chipset Roving Networks WiFi Bee module with 802.11 b/g radio USB Bee module with a CP2102 USB to UART chip Power Supply – 12V/1A via 2.1mm jack with positive core polarity Dimensions – 122mm x 87mm x x 31mm (board) There are also versions with 2 and 8 relays. I kind of wish they had models taking 220V AC input instead […]
Vinclu Gatebox is an IoT Gateway using a Hologram Girl as the User Interface
Let’s face it, home automation or IoT gateways are just boring cubic, rectangular or cylindrical boxes without soul that just transmit packets and gather data between different devices. But don’t despair, as Vinclu, a Japanese start-up, has come up with Gatebox an IoT gateway with a virtual girl, named Hikari Aizuma, that welcomes you back home, turns on the TV on request, wakes you up in the morning and gives the day’s weather forecast, and more! The product is still in development, and we don’t known many details, but the Gatebox is said to uses video projection technologies and various sensors, and you’ll be able to select other characters. The company has raised 90 million JPY (~$770,000 US) and is currently recruiting engineers to complete hardware and software development. The device is expected to be launched at the end of the year via a crowdfunding campaign. You can watch the concept […]
