    The omnipresence of the Internet of Things (IoT)-based accelerom eter in the industry has been considered as an alternative to paper chart recorder yet it is unprecedentedly tested on pressure recording variation. To this end, this paper contributes to the improvement of data acquisition which is obtained from pressure chart recorders through accelerometer de vices. Firstly, the accelerometer device is thoroughly described. Then, the implementation of the accelerometer and IoT based accelerometers in a va riety of domains is discussed. Secondly, the used materials to carry out the bench test are presented, namely accelerometer, ADXL345, H3LIS331DL, Barton , DEWEIT pressure chart recorder, Raspberry pi and Arduino. The aforementioned devices are purposefully coupled, explicitly two types of ac celerometers are plugged into the raspberry pi for the sake of comparing the accuracy of transmitting mechanical to electronic charts. Finally, it is found that the accelerometers combined with wireless communication can offer a reliable alternative for expensive tasks. In addition, it perfectly facilitates data acquisition from a pressure chart recorder which is considered the first integration of an accelerometer in a pressure chart recorder. Interestingly, the H3LIS331DL accelerometer is way better than ADXL345 when it comes to processing high-pressure variation more than 3900 PSI within few sec onds. It is noteworthy to say that the proposed IoT-based accelerometer to assess the pressure variation in industry is considered for the first time as an electrical chart recorder
