Based on the YL105 datasheet specifications, here is a "better" initialization sequence than most tutorials provide.
: For large-scale projects involving sensor networks, you can track your wireless equipment using the Mobility Work CMMS app to manage hardware files and preventive maintenance. yl105 datasheet better
Always refer to the manufacturer’s YL105 datasheet V1.2 for absolute maximum ratings (TMV: -20°C storage, 5.5V absolute max input). Based on the YL105 datasheet specifications, here is
bool readByte(uint8_t* data) uint8_t byte = 0; for (int i = 0; i < 8; i++) while(digitalRead(YL105_PIN) == LOW); // Wait for start of bit uint32_t startTime = micros(); while(digitalRead(YL105_PIN) == HIGH); uint32_t duration = micros() - startTime; bool readByte(uint8_t* data) uint8_t byte = 0; for
: Ensure your code (using libraries like RF24 ) correctly defines the CE and CSN pins. While MOSI, MISO, and SCK are fixed to your hardware's SPI pins, CE and CSN can usually be assigned to any digital pin.
Desolder the LM393 chip. Connect the sensor’s center pad directly to an analog pin (via a 1kΩ resistor for protection). The comparator’s hysteresis ruins precision.
