a flexible sensing device protruding externally from a housing of the electronic sensor for detecting when a barrier monitored by the electronic sensor has been opened, the flexible sensing device comprising a first end coupled to a circuit board inside the housing and a second end hanging in air;
a transmitter for transmitting an alarm signal to a receiver;
a memory having processor-executable instructions stored thereon; and
a processor, coupled to the flexible sensing device, the transmitter, and the memory for executing the processor-executable instructions that cause the electronic sensor to:
monitor, by the processor, an attribute of the flexible sensing device;
generate, by the processor, the alarm signal when the processor determines that a value of the attribute of the flexible sensing device has changed more than a predetermined amount; and
transmit, by the processor via the transmitter, the alarm signal.
