XW-210 WiFi™ Users Manual
2.4 1-Wire Sensor Connections
The XW-210 has a “1-wire” port which supports up to four digital temperature or other Xytronix 1-wire
sensors. The sensors share the same three connections for communications and power (+5V, Ground,
Data). Every sensor on the bus is assigned a unique serial number when it is manufactured. That
number is used to address the sensor during communication.
The digital temperature sensors are interchangeable and require no calibration. The sensors accuracy is
+/-0.5°C (-10°C to +85°C)
.
The temperature sensor is available in several configurations. The
encapsulated version has a stainless steel probe and can be used in outdoor applications however, the
probe is not suitable for immersion or use in pressure vessels. For immersion and other demanding
applications use a thermowell to protect the sensor. The basic sensor (non-encapsulated) must used in
protected locations. The temperature sensors have three wires as shown below.
