Background. Taking into account the temperature of the object by autonomous information and control systems increases the accuracy of their work. The temperature sensors used have an analog output (voltage), which requires conversion to a form suitable for digital processing. In this regard, there is a problem of selecting a sensitive element and determining the simplest and most accurate method of converting its signal. Materials and methods. Various methods of analog-to-digital conversion of the output signals of a semiconductor thermosensitive element are considered. Conclusions. The possibility of using temperature sensors with a semiconductor thermosensitive element and a time-pulse converter of double integration with fixed values of the integration limits in autonomous measuring and control systems has been theoretically and experimentally confirmed. It is shown that the sensor is simplified by excluding the reference time interval from its composition, and the high accuracy of the time-pulse conversion is achieved by the absence of the influence of the instability of the integrator parameters on the measurement results.
