Abstract: A bed check device having a force sensing resistor; a resistor divider; a microprocessor; an analog to digital converter; a power supply; a wireless transmitter; and an antenna wherein the force sensing resistor is in mechanical contact with a bed, such that a change in force to the bed corresponds to a change in its resistance and voltage, which is analyzed and acted upon by the resistor divider, microprocessor, analog to digital converter, power supply, wireless transmitter, and antenna.
