PLACEMENT
• The remote sensor should be placed under eaves or a similar
location with free air circulation sheltered from direct sunlight and
extreme weather.
• Ideally, place the remote sensor over soil, rather than asphalt which
would cause false readings.
• Avoid placing the remote sensor near sources of heat, such as chim-
neys and heating elements
• Avoid areas that collect heat from the sun and radiate heat, such as
metal, brick or concrete structures, paving, and patios
• The international standard for the valid air temperature measurements
is 4 feet (1.25meters) above the ground
REMOTE TEMPERATURE AND HUMIDITY SENSOR (TS21):
• Remote data transmission to the main unit via 433 MHz frequency
