Home Healthcare Technologies and Services: Heart-Rate Fetus Monitoring System Using an MCU ESP8266 Node

In this paper, a preliminary implementation of a system monitoring the fetus’s heart rate (FHR) has been designed and implemented as a mobile wearable measuring system with remote sensing specifically developed on Node MCU ESP8266 (ESP). In particular, the proposed system uses sensors for heart rate, humidity, temperature, and a transceiver module. The transceiver module is capable of efficient data transmission to a remote server station using an IEEE 802.11 b/g/n protocol—based on the wireless network. A major benefit is that the patient’s data is monitored at distance using an IoT device. Hence, it complies with the health safety distance measures required due to various situations, including that of the COVID-19 pandemic. The proposed implementation has been proven to be efficient in terms of hardware simplicity and cost-effectiveness and is accompanied by preliminary accurate measurements of the FHR.
