They operate on 5V logic, with some also supporting 3.3V. The DHT11 and PIR require one digital pin each; the ultrasonic uses two pins (trigger, echo); the IR and soil sensors use one digital\/analog pin. Common libraries: DHT.h, NewPing.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 5V and GND to common ground. For the ultrasonic sensor, trigger to pin 9, echo to pin 10. PIR sensor output to pin 2, with a 10-second delay on startup. DHT11 data pin to pin 4 with a 10k pull-up resistor to VCC. Soil sensor analog out to A0.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
