Playing around SigFox network with Akeru board

Laisser un commentaire

Last week, I had the chance to attend the SigFox maker’s tour in Paris, it was very interesting to learn more about this amazing technology.

SIGFOX is the first and only company providing global cellular connectivity for the Internet of Things, fully dedicated to low-throughput communications. SIGFOX is re-inventing connectivity by radically lowering prices and energy consumption for connected devices.

After the event, everyone has got a Akeru Sigfox board with one year contract, (ready to send messages to the SigFox network), the board is available in snootlab website for 100€ and is compatible with Arduino,

I ‘m currently do some experimentation with this board, more infos soon.

ArduiHome redesigned with EasyIoT libraries

Un commentaire

Since I have discovered EasyIoT lib, i consider to redesign completely ArduiHome project. EasyIoT librarie support ESP8266 wifi , and NRF24L01+ shield, the wireless probe pcb will be use, with minor modifications.

I plan to use:

Temp/Humid sensor DHT22 for two bedrooms, and only Temp sensor for kitchen, bathroom, living-room, and maybe one sensor, Temp/Barometric Pressure for outside.

Also, somes security sensor’s like Carbon monoxide MQ7, and Gas Town MQ5/MQ6 will be add with use of SMS API from my mobile phone provider.

The server will run with EasyIoT server with a RaspberryPi2-1Gb, and a 4×20 LCD screen to display informations from sensor.

Wireless RF probe for Arduihome

3 commentaires

Update [17/02] – Project redesigned, look this following post.

Update 27/01, I ‘ll finally use ESP8266 chip, for the same cost, Wifi connections on the probes will be more flexible, eliminate any constraints, quantity of probes, signal multiplexing, and data exploitation …

Under development, some wireless probe in the goal to send data’s, temperature and humidity level directly to arduino, with displaying on a 2×8 LCD in live, using NRF24L01+ RF chip and DS18B20, DHT22 probe. The board is compatible with both. Continuer la lecture de Wireless RF probe for Arduihome →

Ardui’Home, temperature and gas alert for home

4 commentaires

Update [17/02] – Project redesigned, look this following post.

Update [2/06] – I’m working on a wireless version

I’ll move in a new apartment very soon, and i have the idea for a new domotic project, ArduiHome, a Arduino Uno, GSM/GPRS Shield, some sensors to measure temperature, humidity, and gas.

The goal of this project is to display, on a LCD, the temperature from four areas.
Sending back temperature and/or humidity value via SMS (no needed at this moment).
Send an alert when town gas or carbon monoxide reach a critical level.
Drive a relay to turn on lighting, or heating system (no needed at this moment). Continuer la lecture de Ardui’Home, temperature and gas alert for home →
