Title: Need help on Home Automation Wiless Communication Post by: puta on August 14, 2011, 03:48:43 03:48 I am building a project home automation system, and trying to use PT2262/ PT2272 for coding and decording the data. I need to modulate the signal from PT2262 with 'Surface acoustic wave' (SAW) resonators, and extract the signal and feed to 2272 for decording, as it seems a low cost solution and very useful in home automation. I found some SAW resonators (eg 315Mhz) but could not find the details on how to integrate the SAW with the PT2262, and demodulate/ decode at the receive end. Here is a link to the 315 Mhz (LR1 315.00) SAW: http://www.szqitong.com.cn/product_show.asp?id=220 Transtated: http://translate.google.com.au/translate?hl=en&sl=zh-CN&u=http://www.szqitong.com.cn/product_show.asp%3Fid%3D220&ei=xDNHTpirFaybmQWnr9TMBg&sa=X&oi=translate&ct=result&resnum=1&sqi=2&ved=0CCMQ7gEwAA&prev=/search%3Fq%3DLR1%2B315.00%26hl%3Den%26biw%3D1680%26bih%3D965%26prmd%3Divns I have noticed this combination is used in most industrial wireless atomation systems, and would be very useful to develop one.
