Temperature/Humidity Sensor Connection (WebRelay-10 Plus™ only)
Temperature and/or humidity sensors can be used for monitoring environmental conditions. The digital
sensors use a one-wire data bus, which allows up to eight sensors to share the same terminals (+5V,
Ground, Data). Every sensor on the one-wire bus is assigned a unique serial number when it is
manufactured. That number is used to address the device during communication.
The sensors have three wires; the wire color is show in the table below.
