4.3: Connection with DS18B20
The DS18B20 sensor may easily be installed wherever very precise
temperature measurements are required. If proper protective meas-
ures are undertaken, the sensor may be used in humid environments
or under water, it may be embedded in concrete or placed under the
floor.
You can connect up to 6 DS18B20 sensors in parallel to SP-SD
terminals.
1. Disconnect power.
2. Connect with the diagram below:

3. Verify correctness of connection.
4. Power the device.
5. Add the device to the Z-Wave network.
4.4: Connection with DHT22
The DHT22 sensor may easily be installed wherever humidity and
temperature measurements are required.
You can connect only 1 DHT22 sensor to TP-TD terminals.
1. Disconnect power.
