An electric power driven system for monitoring a device or sensor for detecting the presence of a load, such as a patient, infirm person or infant, on a device or sensor. The system includes a microprocesso r and a plurality of circuits connected to the microprocessor. A circuit connected to the microprocessor and to the sensor automatically initiates operation of the microprocessor upon detection by the sensor of the load's presence on the device or sensor. Another circuit connected to the microprocessor provides a signal or alarm upon demand by the microprocessor. A circuit connected to the microprocessor is adapted to be interfaced with a nurse call station for generating signals to the station upon demand by the microprocessor. A circuit connecte d to the microprocessor programs the system in response to commands manually applied to this circuit.
