A fetal health monitoring belt includes a main body and a fixing part, wherein the main body includes an ultrasonic sensor, at least one ECG sensor and a microcontroller which includes a control module, a signal processing module and a data transmitting module, and the control module electrical connects the ultrasonic sensor. The ultrasonic sensor detects the location of the beating heart of the fetus, and transmits a location signal to the control module. The control module receives the location signal and transmits a detection signal to the corresponding ECG sensor. The ECG sensor detects the ECG signal and processes the signal by the signal processing module, and transmits the signal by the data transmitting module.
