Yl105 Datasheet Guide

The YL-105 is a low-cost, low-power wireless transceiver module designed for various short-range wireless applications. It is based on the RF chip by AMICCOM. It operates in the 2.4GHz ISM band (Industrial, Scientific, and Medical frequency band).

If your YL105 is in a standard , the layout is usually as follows: AC (~): Input for the alternating current. AC (~): Second input for the alternating current. Positive (+): Rectified DC output (High). Negative (-): Rectified DC output (Ground/Common).

In the burgeoning field of environmental monitoring and smart agriculture, the ability to digitally quantify the clarity of a liquid is a fundamental requirement. While industrial water quality stations utilize nephelometers costing thousands of dollars, the hobbyist and prototyping markets rely on accessible, low-cost alternatives. Chief among these is the .

Many datasheets for YL-105 show:

The heat hit the polyolefin. The yellow sleeve didn't just melt; it tightened with mechanical precision, gripping the cable in a flame-retardant, fluid-resistant embrace. Within seconds, the frayed danger was entombed in a semi-rigid, yellow shell.

The YL-105 layout splits into an (male 0.1-inch header pins for the microcontroller) and an output socket (female 2x4 IDC connector to receive the nRF24L01+ module). Unlike the power pins, the SPI logic lines pass straight through. They do not require logic-level conversion because nRF24L01+ input pins are natively 5V tolerant.
