Infant motion sensor that detects a baby's movements. - Brand: BabySmile - Model: E-202 - Function: Infant motion sensor - Awards: BABYTECH AWARDS 2024 - Target age: From 0 months - Usage: Can be used as a medical device - Features: Detects movement during sleep Thank you for viewing. I have used this for about 8 months, so the battery is almost dead. You will likely need to replace it soon after purchase, so I've priced it affordably. If you purchase this with item ①, which is also for sale, I will discount the total by 1,000 yen. Thank you.
