  Quote  It will be interesting to see how well it recovers from prolonged high humidity.

There are a few new accurate, affordable T & H modules now available. One that got my attention is the TI HDC1080 I2C.
  Quote  8.3.3 Heater
The heater is an integrated resistive element that can be used to test the sensor or to drive condensation off the sensor.
The heater can be activated using HEAT, bit 13 in the Configuration Register. The heater helps in reducing the accumulated offset after long exposure at high humidity conditions.
Once enabled the heater is turned on only in the measurement mode. To accelerate the temperature increase it is suggested to increase the measurement data rate.

At this stage I don't have a use for another so won't get one.

After lengthy comparison with the AHT10 it seems my effort to revive the DHT11 have only been partially successful, the humidity is off by 10% to 20%, varying with temperature.
