A wireless sensor includes a radio frequency (RF) front end, a sensing element, and a processing module. The RF front end receives a request for sensed data from a sensing computing device and sends a coded digital value to the sensing computing device via the RF signal. The sensing element senses an environmental condition of an item. The processing module determines an effect on an operational parameter of an RF front end of the wireless sensor as a result of the sensing element sensing the environmental condition and while receiving the RF signal. The processing module also adjusts tuning of the RF front end to mitigate the effect on the operational parameter and equates an amount of adjusting of the tuning of the RF front end to a coded digital value.
