DHT22 reading -459?

Using Arduino Programming Questions

Does anyone else have issues with DHT22 throwing random crazy temps?

I send dht22 data every minute via MQTT to node red and throw it in influxDB.

float t = dht22.getTemperature() * (9.0/5.0) + 32.0;
float h = dht22.getHumidity();

anyway, I added some code to hopefully resolve...or....recheck reading.

float t = dht22.getTemperature() * (9.0/5.0) + 32.0;
    if(t < -100){
      //check temp after faulty reading. been getting -459.3999939 at random.
      delay(2000);
      t = dht22.getTemperature() * (9.0/5.0) + 32.0;
    }

Your DHT22 is connected to a device that resets.
