Differences between 2 products

Post by kmcook »

Can someone tell me what the difference is between these 2 PIR sensors?

https://www.adafruit.com/product/4666 - Mini Basic PIR Sensor - BS412
https://www.adafruit.com/product/4667 - Mini Basic PIR Sensor - BL412

I thought it might have been the detection distance such as S for short and L for long, but they both say the same length and angle.

The difference is the size of the sensing element, and thus the sensitivity. This is mentioned on the two product pages.
