Yl-105 Datasheet [extra Quality] «COMPLETE × Anthology»

If the measured humidity the threshold, the DO pin goes HIGH . 5. Interface Guide: Connecting to Arduino

void setup() pinMode(sensorPin, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(sensorPin), countPulse, FALLING); Serial.begin(9600);

The performance of the YL-105 module is largely determined by the capacitive or resistive sensor element it uses. Specification 3.3V - 5V DC Current Consumption Humidity Detection Range 20% - 95% RH Humidity Accuracy ± 5% RH (typical) Operating Temperature 0°C to 60°C Response Time < 10s (63% response) Digital Output Type TTL Level (Low/High) Analog Output Type 0V - VCC (Variable) Comparator IC 3. Pinout Configuration yl-105 datasheet

📐 : Roughly 26mm x 19mm , making it ideal for breadboards or small enclosures. 🛡️ Version 2: YL-105 Infrared Motion Sensor Alarm

The 8-pin female socket directly replicates the nRF24L01+ layout. When the transceiver is inserted into the YL-105 socket, the regulated 3.3V power is delivered cleanly to the module's VCC pin. The SPI control lines ( SCK , MOSI , MISO , CSN , CE , IRQ ) pass directly through the adapter to the host MCU. Schematic and Circuit Architecture If the measured humidity the threshold, the DO pin goes HIGH

High-efficiency AMS1117-3.3 regulator ensures the wireless module receives stable power. Filtering Capacitors:

const int sensorPin = 7; // Digital input const int ledPin = 13; // Built-in LED Specification 3

Independent direction of rotation, featuring a drive sleeve transmission. Pressure & Temperature:

As moisture accumulates, the sensor's conductivity increases, causing the analog output voltage to decrease (or increase, depending on the module configuration).

This sensor is generally not suitable for extreme moisture condensation conditions or very precise laboratory applications. If you'd like, I can: Show you a schematic for the relay circuit. Provide code for calibrating the sensor .

For precise measurements, you must calibrate the sensor by measuring its analog output in known low and high humidity environments and mapping those values in your code.
