Based on the YL105 datasheet specifications, here is a "better" initialization sequence than most tutorials provide. void loop() // Check if data is available
Unlike sensors offering only analog output, the YL-105 provides both RS485 digital communication and 4–20mA analog signals. This dual-output design means you can integrate it with legacy PLC systems using analog inputs or modern SCADA systems using MODBUS-RTU protocol. The is a breakout and voltage regulation module
The is a breakout and voltage regulation module designed specifically for the widely used NRF24L01 2.4GHz wireless transceiver . The core purpose of the YL-105 is to bridge the electrical gap between standard 5V microcontrollers and the stricter 3.3V power requirements of the radio frequency (RF) transceiver.
The FST100-YL-105 variant from First Sensor is engineered for multiple challenging environments:
