To implement surface detection capability in the ABCLMR we had mounted an Infrared Surface Detection Module (ISDM) in it separately. To design a simple but efficient ISDM, a standard Sony TV remote was used infrared Pulse Width Modulated [PWM] [14] wave generation. The ISDM was implemented with 38.7 Khz subcarrier frequency. Using the subcarrier of 38.7 Khz it is possible to avoid noise interference with the base band signal coming from sunshine, tube light and other ambient light sources [15]. To generate a continuous reference IR wave for surface detection, the STAND BY key of the Remote was fixed to the ON state.
