Where do you find out about technology for seniors (hearing aides, automated home sensors, etc.) and compare products to make a decision?

Browse "assistive technology for seniors" on the web. Or, you can ask here for what you need help with, and also get scads of good suggestions. For example: people were talking about the walk in bathtub issues, and I asked if you have to drain the water from the tub before getting out; answer, yes. I then did not have to call the company and be inundated with sales calls from then on. Worked for me!

Amazon is where I just ended up looking. After getting on the web and entering even the simplest question(s), then just clicking what looks right, a parade of products are pictured, with descriptions. For example, enter "walk-in batubs for seniors." This is not a recommendation for Amazon, there are other vendors for the same products. Then, when you are just browsing the web for unrelated topics, these same products will just pop up continually. That can be irritating. Windyridge is soooo right, scads of hits.

Its very easy to Google specific items. Like, clocks for elders, or lift chairs for elders etc. you'll get scads of hits .

Try to make your search a little more specific, for example "mobility aids" or "adaptive clothing" and narrow the scope of search. If you go up to the search site box and enter "technology" you will see what I mean.
