The heart-to-heart toilet of Guangzhou Yifeng Health Technology Co., Ltd. can detect health signs such as heart rate, ECG, blood pressure, oxygen saturation, body temperature and respiratory rate, which is particularly practical. For cardiovascular diseases easily caused by sub-healthy people and the elderly, this product can also monitor all data and take timely measures. You can find their official website in Baidu.
