Abstract
A pressure sensitive pad configured to be placed under a mattress and configured to identify presence and absence of a threshold weight on the mattress. The pressure sensitive pad comprises a signal generator, a sensing zone, at least one variable matching resistor, a microcontroller unit (MCU). The signal generator configured to generate an electrical signal. The sensing zone has a sensing resistor with a first resistance which varies depending on a pressure applied on sensing zone. The variable matching resistor is in series with the sensing resistor and the signal generator, the variable matching resistor having a second resistance. The MCU has an analog-to-digital converter (ADC) configured for receiving and measuring a portion of the signal at an electrical junction between the sensing resistor an the at least one variable matching resistor, the MCU being configured to control the second resistance of the at least one variable matching resistor.
