I've been using these:

amazon.com/gp/product/B0CCF3HYT9

The sensing angle is about 100 degrees but you do get six of them along 
with mounting brackets. Also the output is digital not analog. There are a 
number of other options but I think the all use the same sensor. It's 
adjustable for range and sensitivity.

https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/
overview

has information on how they work and some of the adjustments. The ones I 
have are very close to Adafruit's new design. Follow the pages and there 
is a simple diagram with batteries, the module, and a LED, no Arduino. You 
could do something like that but drive a FET to control the main LED.
