7.2. Problems in the temperature sensor module
The receiver receives signals from sensors, but fails to registrate signals from one
sensor in particular.
Potential problems:
- Batteries are missing or are at a low charging level
E - Reversed polarity of the sensor's batteries
- The sensor's location is outside of the receiver's reception range
N
- Damage to the sensor (by corroded battery contacts,
moisture or battery leakage)
G
- Problems in the radio signal communication
L
Suggested solutions:
- Insert fully charged batteries in the sensor and repeat the
I
communication test (please check the polarisation of the
S
batteries before inserting!!)
- Check the battery contacts and remove all corrosion and
H
moisture effects.
7.3. 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 be located on a metallic surface
- Sensor or receiver are situated in locations with high humidity
- Windows between sensor and receiver may contain several
layers of glass or 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
