In this paper, we propose an electric cell-substrate impedance sensing system that can be accessed from the internet. The hardware specification was derived using numerical simulations and culture chamber impedance emulators, and the impedance calculation methods were compared. In addition, we propose server-type software to easily control and monitor the system from the internet. Experimental results show that it is advantageous to use an acquisition device of 50 mega samples per second or more and to calculate the impedance using a sine fitting method rather than the lock-in detection method that is generally used. During experiments, there was no problem accessing the proposed server from the outside with standard computing devices.
