RPM MEASUREMENT AND CALCULATIONS USING TSOP IR RECEIVER

Ajinkya Chouthai, Rathin Karhu, Soham Kulkarni

This paper illustrates a new method of measurement of revolutions per minute (RPM) using TSOP IR receiver. The principle of opto-coupler is used in measuring RPM in the infra-red (IR) range wherein TSOP is the IR receiver. New terms for RPM measurement have been defined which assist in calculating maximum RPM. The maximum RPM that can be measured using this method is over 140,000 for TSOP 1756.This method of RPM measurement can be used having significant advantages like compact size, accuracy, wide range of values and low cost.
