This page lists some sensors that could be possibly used with the driver.
Temperature and Humidity
- MMA7260QT 3-axis Accelerometer
- note that it is a 3.3V and you need a logic converter circuit to connect it to analog input on Arduino.
- MMA7455 3-axis Acceleerometer
- Hitachi H48C Tri-Axis Accelerometer
- Wii Nunchuck could be another interesting option and can be easily connected to Arduino with the WiiChuck Adapter
- Sharp GP2Y0A21YK IR proximity sensor
- Ultrasonic range finders from Maxbotix or Maxsonar
