SENSOR
This product can work with up to 3 sensors at any one time
to capture temperature and relative humidity readings in
various locations around the home.
A complete set of 3 sensors are provided in this package,
while replacement wireless remote sensors can be
purchased separately.

This sensor conveniently displays the temperature /
humidity which makes it especially suited for locations
where you would like to see this data at a glance without
having to refer each time to the main unit, such as
children’s room.
