Gertboard DHT22

I have a question if it is possible to connect the temperature sensor DHT22 at Gertboard.

The i/O ports from specifications are working only in one direction IN or OUT and the DHT22 sensor needs a start signal and after that outputs 40 bits.

Did anybody read the DHT22 sensor using Gertboard.

I am interesting about the Gertboard wiring and the pins where is connecting DHT22 sensor.

Here is a link that shows how to connect the Raspberry pi to the DHT22 http://rpi-experiences.blogspot.com/2013/07/rpi-monitor-use-dht11-or-dht22-humidity.html
