1. Temperature monitor
When the PIR sensor detects motion, the Pico activates the fan motor. You can also program the fan to oscillate using a servo for better air coverage.The DHT11 sensor monitors humidity, and the Pico controls the fan based on preset thresholds. This ensures the fan runs only when needed, reducing electricity usage.💡
Boost your home’s security with a Raspberry Pi Pico-based burglar alarm system. Created by Miftahul, this device detects motion near entry points and alerts you to potential intrusions, making it ideal for smart home security setups.Based on the RP2040 chip, it’s packed with features like GPIO pins, I2C, SPI, UART interfaces, and programmable I/O.
2. Automatic plant watering system
Whether you’re a seasoned DIYer or a beginner, the Pico is a gateway to countless creative projects. This project is a cost-effective alternative to commercial oscilloscopes.

My thoughts
Automate your bathroom fan to turn on only when necessary. This system detects high humidity levels and activates the ventilation fan, preventing mold growth and improving air quality. The PIR sensor detects movement and sends a signal to the Pico, triggering the buzzer. Enhance this setup with Wi-Fi for mobile notifications or add bright LEDs to deter intruders.In this project by Craig Richardson, the lights automatically illuminate when someone approaches, providing visibility while saving energy. This is especially useful for families with kids or elderly members and adds a modern touch to any home.Tired of forgetting to water your plants? The project Sploosh uses the Pico to monitor soil moisture levels and automatically activate a water pump when needed.
