A fall detection device (10) which comprises two identical housings (11), each containing an identical pressure sensor (12) housed within a suitable recess (13) of the corresponding housing (11). The housings (11) are mounted on a printed circuit (14) using electrical connection pins (15). The two sensors (12) are arranged coaxially head to foot and communicate directly with the ambient air in order to output a measurement of the atmospheric pressure value. The sensors are arranged so as to generate a signal based on the measurements utilized for detecting a fall, and comprise a unit for transmitting the signal to a transmission station as an alarm signal.
