Increase pull down time for DHT22 sensor to 2.5ms

Open Sly1024 opened this issue 5 years ago • 0 comments

Based on this comment for DHT11: https://github.com/momenso/node-dht-sensor/issues/67#issuecomment-365784215 And this datasheet: https://www.sparkfun.com/datasheets/Sensors/Temperature/DHT22.pdf#page=6 I tried 1ms (1000 us) pull down time, but it was not enough. A 2ms (2000 us) time seemed to be OK, but to be on the safe side I set this to 2.5ms (2500 us).
