It's not always nice to have to wait until the smell of your baby's poo fills the room before you realise they need a nappy change. This nappy monitoring system will send a message to your phone before your baby sends one to your nose. 

Parents will know what it's like. Having a baby involves asking yourself – and your partner – "Do I smell poo? Do you smell poo? Did she poo? Am I just imagining it?"
