5.3. Radio signal transfer problems
The receiver system is missing signals from one or more sensors, or only
receiving a limited number of signals.
Potential problems:
-
Walls or ceilings between sensor and receiver may contain
metallic constructions.
-
Sensors and/or receiver may is located on or by a metallic surface
-
Sensors and/or receiver are situated in locations with high humidity
-
Windows between sensor and receiver may contain several layers
of shielding materials or may be covered by humid moisture.
-
Other 433MHz systems may be working within the 20m
operating range
-
Interference or jamming signals from radio or TV transmitters
-
Electronic or electrical equipment (eg. computer equipment or
magnetrons), operating within the 2-5m operating range
-
Low power level of the sensor’s batteries (see 2)
Suggested solutions:
-
Modify the locations of the sensor and/or the receiver
-
Remove the interfering equipment
5.3.2. Communication test
A simple test will check the communication channel between sensor and
receiver:
1.
Remove the batteries from the sensor
2.
Locate the sensor at ca. 1 m distance to the receiver
3.
Insert the batteries in the sensor
4.
A correctly working system will show the according sensor entry
to the sensor list within 5 seconds.
