I need a thermometer alarm!

My husband leaves doors and windows wide open and forgets about them. in the middle of winter this is ESPECIALLY awful. Two nights ago he left the back door wide open (again) and luckily I realised it when I went down at midnight for a snack. He wants to exchange the air. That is his motivation. Is there a thermometer that will sound an alarm if it senses the temperature going below 21 celcius (for example)?
