DHT22 temp & humidity sensor issues

I've tried 2 different sensors and both freeze up randomly. The only way to get them going again is to un-plug/re-plug them. Is there a fix for this or an alternative sensor..?

Hi @GarrickG sorry to see it's giving you issues, are you using a DHT22? The DHT11 won't work. I had one running for months without issues.

Did you set the pullup/pulldown resistor jumper on the sensor port to P/U? If that isn't set it could lock up.
