Facing some problem in a small home automation project

Sat Apr 30, 2016 5:45 am

Hello everyone,

I am a newbie in IoT and applications of Raspberry Pi.
I am working on a small home automation project which consists of following sensors:
1. Pressure
2. Proximity
3. Temperature
4. Current
5. Vibration

I have codes for all the sensors and I can read sensor data when they are connected to RPi GPIO.
But, I want to place these sensors in different rooms (as it's a small part of home automation).
I don't understand how to read sensor data on Rpi when they are at different locations.
I have some questions:
1. Can you suggest me which wifi module should I use for sensors and which for RPi?
2. Can wifi module transfer sensor data to raspberry pi?
3. I have all the sensors, RPi and other required equipment except Wifi Module.
I am able to get sensor data when sensors are directly connected to RPi.
As per your suggestion, which wifi module should I purchase?
Will it be compatible with all the sensors?
4. Do I need Arduino Uno?
After surfing the internet I came to know about ESP8266 wifi module,
* Can ESP8266 transfer sensor data to raspberry pi?
* Does it require to have a mediator like Uno dev board to transfer data?

I'm not a pro, but I'd suggest using the ESP8266 and a MQTT broker/publisher.

Found a link here which seems like a good guide, but use this to start your research.

Its not very efficient and it may be more expensive, but you could buy multipule RPi zeros.

The best solution is esp8266
The best module I tried is this: http://www.wemos.cc/Products/d1_mini.html . It is cheap and can be programmed with arduino IDE with esp8266 library. I am very satisfied with this product :)

I'm quite happy with panStamps http://panstamp.com/ for remote sensors :)

Just following up on this, I am trying to accomlish something similar I.e. Monitor temps, control lights in multiple rooms etc. however I don't understand what I need from a wifi communication standpoint to point back to one raspberry pi which would control each device around the house. Again looking for input.

Thanks
