I've been working with a Raspberry Pi and the wired DHT-22. I wanted to place the sensor(s) a fair distance away from the RasPi, but found the data was not correct. In order to receive the correct data, I added a delay just prior to the loop that checks for the GPIO pin to go low. I did not submit a patch, as I suspect the delay will be different for each installation. usleep(4); This small delay allows both the remote sensor (~60 ft away) to read properly, and does not affect the sensor connected via a Pi Cobbler. No other changes to the code were required. |
