5.2. Reading and Writing User Registers

There is one user register on the TH06 that allows the user to set the configuration of the TH06. The procedure

for accessing that register is described below.

The checksum byte is not supported after reading a user register.

5.5. Heater

The TH06 contains an integrated resistive heating element that may be used to raise the temperature of the

sensor. This element can be used to test the sensor, to drive off condensation, or to implement dew-point

measurement when the TH06 is used in conjunction with a separate temperature sensor such as another TH06

(the heater will raise the temperature of the internal temperature sensor).

The heater can be activated using HTRE, bit 2 in User Register 1. Turning on the heater will reduce the tendency

of the humidity sensor to accumulate an offset due to "memory" of sustained high humidity conditions.
