This would contain contents about sensors, Arduino MCU, etc.
1. https://www.tartssensors.com/ (Wireless Sensors)
Wireless sensors of this website can be connected to both Raspberry Pi and Arduino. Additional product called 'Gateway' for Raspberry Pi and Arduino seems necessary when we connect wireless sensors to processor. Also we should buy antenna and battery for gateway and sensors.
- Tarts Arduino Shield ($44.95)
- Interfaces with Arduino Uno, Leonardo, Yun, Ethernet, Due, MEGA
- 250 - 300 ft. non-line-of-sight RF range
- Tarts Raspberry Pi Plate ($44.95)
- Interfaces with Raspberry Pi Boards
- 250 - 300 ft. non-line-of-sight RF range
For sensors, we can basically think about accelerometer to detect earthquake, and we can additionally add temperature/humidity/gas sensors. Especially sensors from this website is wireless, so we should consider about battery life. It seems battery life of each sensor is about 1-2 years. Maybe we can additionally make an alarming system for low battery state, or just attach photoelectric cell.

2. http://www.phidgets.com/ (USB Sensors)
Sensors in this website supports USB connection. Maybe we can directly connect it to Raspberry Pi with an USB hub.
This link(https://phidgets.wordpress.com/2015/02/02/what-you-can-do-with-raspberry-pi-and-phidgets/) says that the USB port of Raspberry Pi does not provide enough power to the Phidgets, so it seems that we need additional powered USB hub.
- PhidgetSpatial Precision 0/0/3 High Resolution ($80)
- High precision when measuring acceleration within ±2g
- Precision Temperature Sensor ($15)
- Temperature sensor with a range of -30°C to +80°C with a typical error of ±0.75°C in the 0°C to 80°C range.
- Measures the ambient temperature in the area surrounding the board
3. http://store.linksprite.com/This web store provides some basic components about Arduino, Raspberry Pi. We can check datasheet of each component.
- Breakout Board for ADMP401 MEMS Microphone ($8.95)
- Breakout of DHT 11 Temperature and Humidity Sensor ($5.20)
