Wireless Temperature and Humidity Sensors
STW-6010, STW-6014, THW-1102
Specifications and design subject to change without notice.
Mounting
Select a location
Install the sensor on an inside wall where it can
sense the average room temperature. Avoid locations
with direct sunlight, heat sources, windows, air
vents, and air circulation or obstructions such as
curtains, furniture, etc.
◆
◆
Mount the sensor in an area with a minimum
illumination of 200 lux for three to four hours
everyday. The light source can be either artifical
or daylight. The health and safety at work act
requires a minimum illumination of 500 lux for
office workplaces.
◆
◆
The long term illumination should not exceed
1000 lux.
◆
◆
Avoid recessed areas that are not sufficiently
illuminated throughout the day.
◆
◆
When using collimated artificial light the angle
of incidence on the solar cell should be not too
steep.
◆
◆
The sensors can be mounted with the solar cell
toward a window but not in direct sunlight.
Even occasional direct sunlight can lead to false
temperature values.
◆
◆
Consider the future use of the room and avoid
locations that may be used for filing cabinets,
shelf units, or other large obstructions.
◆
◆
In closed spaces with several walls, the maximum
range may be less than 33 ft (10 m). In open areas,
place the sensor no farther away than 98 ft. (30 m)
from the receiver or gateway. See the publication
Planning Guide For Wireless Sensor Networks
for
details.
Remove the sensor body from the back panel
The sensor body is held to the black, back panel by
three, small, round pegs that fit in the holes of the
sensor body. The bottom peg is a spring tab and
snaps into the center bottom hole.
1. With a small Phillips screwdriver or hex wrench,
press in and hold the tab button that snaps into
the center hole on the bottom cover.
2. Carefully pull or pry the back panel from the
sensor body.
Install the optional battery
A single CR1225 lithium coin battery may be
installed for locations that do not have enough
sustained light to maintain sensor operation.
3. Remove the sensor body from the back panel.
4.
Position the CR1225 battery with the plus (+)
symbol visible.
5.
Slide the battery into the battery holder.
6. Install the sensor.
