The may not exist as a single document from one manufacturer, but by combining the 49E Hall sensor datasheet, LM393 comparator datasheet, and the module’s typical pinout, you have all the information needed to master this device. Its combination of analog and digital outputs, adjustable sensitivity, and low cost makes it a staple for magnetic proximity sensing, RPM measurement, and position detection.
The designation typically refers to two common electronic components found in hobbyist and industrial circles: an nRF24L01 wireless module adapter board Go to product viewer dialog for this item. and a humidity/soil moisture sensor relay module . 1. YL-105 nRF24L01 Adapter Board
Remember:
If you need a reliable receipt of signals from standard wireless remotes or sensors, the is the superior choice over the cheaper "green board" receivers.
The YL-105 datasheet highlights several key features that make it an attractive choice for designers and engineers: yl-105 datasheet
