One of the supporting services in health facilities is medical gas installation. Failure to provide gas is a serious challenge due to uncontrolled gas pressure due to inaccuracies and difficulty in reading medical gas pressure. A clear pressure reader and centralized supervision are needed to improve the medical gas system, so a seven-segment gas pressure monitoring plan is needed and can be monitored centrally. By using PX2 and MPX5700 pressure transducers controlled by Atmega 328 supported by computers using NRF as signal senders and receivers. Can use medical gas can be monitored properly. By using this medical gas pressure monitoring tool, 3 bar, 4 bar and 5 bar medical gas pressure testing is carried out. For medical vacuum at pressures of 40 cmHg, 50 cmHg and 60 cmHg. According to tool making and trial that are conducted, it concludes that the tool works well on demonstrating the pressure on the display of seven segments or the display on computer. The error is still under tolerance as the number of error is 3% and the number of the maximum error limit is 5%.
