Yl-105 Datasheet

void loop() // Calculate RPM every second // ...

Important consideration: the nRF24L01+PA+LNA variant consumes more current than the standard module. When using this high-power version, an external power supply may be necessary because the Arduino's 5V pin may not handle the current peaks during transmission. With appropriate external power connected through the YL-105 regulator, communication ranges up to 1.1 kilometers are achievable.

By turning the potentiometer, you set the reference voltage. When the Hall sensor’s output exceeds this reference, the comparator’s output toggles. This allows you to adjust the magnetic threshold distance. With appropriate external power connected through the YL-105

Weather stations, soil moisture control (in some setups), greenhouse management, and environmental monitoring. 2. Technical Specifications (YL-105 / HR202 Module)

is a popular, compact, and indispensable breakout adapter board designed specifically for the 2.4GHz wireless transceiver module. While the nRF24L01+ module itself operates at a strict 3.3V, many prototyping platforms (like Arduino Uno) operate at 5V. The Go to product viewer dialog for this item.
