I’ve got a board marked "HW-133-v1.0" and I’m trying to find a proper datasheet. I think it’s a PIR motion sensor module (similar to HC-SR501), but the pinout and jumper settings seem a bit different.

The is most commonly identified as a Rain Water Level Detection Sensor Module . It is a low-cost, analog/digital output board used to detect the presence of water, rain, or the liquid level in a container. The "v1.0" indicates the first major revision of the hardware design.
