1.2. 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

- Reversed polarity of the sensor’s batteries

- The sensor’s location is outside of the receiver’s reception

range

- Damage to the sensor (by corroded battery contacts, moisture

or battery leakage)

- Problems in the radio signal communication

Suggested solutions:

- Insert fully charged batteries in the sensor and repeat the

communication test (please check the polarisation of the

batteries before inserting!!)

- Check the battery contacts and remove all corrosion and

moisture effects.
