What You Can Build With This
- Smart home security system with PIR motion alerts and ultrasonic intruder detection
- Automatic plant watering system using soil moisture sensor and relay
- Weather station logging temperature, humidity, and rain detection
- Obstacle-avoiding robot with IR and ultrasonic sensors
Compatibility
All sensors work with Arduino Uno, Mega, Nano, and ESP8266/ESP32 boards. 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.
Wiring Notes
Connect 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.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi?
Yes, with 3.3V logic level converters for the ultrasonic and PIR sensors. The DHT11 and soil sensor work directly with 3.3V.
Does it include sample code and datasheets?
All components come with link to online datasheets. Sample Arduino sketches are available on our support page.
Can I use this kit for a school project?
Absolutely. The sensors are pre-soldered and ready to use, with standard pin headers for easy breadboarding.
