The sensor pad contains a sensor that captures even the baby’s smallest movements. Its service life is two years, then the sensitivity decreases. Therefore, on expiry of this period, it is essential to buy a new pad for the breathing monitor. The old pad cannot be "calibrated" and its use safely prolonged.

If you are using a sensor pad for more than two years, you are at risk of it not responding properly. For example, if you have another baby after a while, simply buy a new pad; of course you can use the original control unit.

There is also a risk when buying second-hand. Even if the sensor pad is only twelve months old, you never know how the previous owners treated it. If it fell to the ground, for example, the sensor could be damaged.
