XW-110™ WiFi Temperature Sensor Users Manual
2.2 Power / Batteries
The XW-110 is powered from either a 5-volt DC wall transformer or two internal 1.5V “AA” batteries. If
the wall adapter is connected, no power is drawn from the batteries. If the external power fails the
module automatically switches to the internal batteries. No jumpers or switches are needed. The wall
adapter should be used for certain modes with high current demands such as: “Stand-Alone mode” with
HTTP server enabled, “Slave mode” with high reporting rates, or when “access point” is active.
Install the batteries as shown. Observe the “+” and “-” markings molded in the enclosure underneath the
batteries. Both batteries should be replaced at the same time. Do not install the XW-110 inside a freezer
or where low temperature conditions would severely diminish the battery capacity.
