Abstract: A sensor is provided that is capable of sensing a level of a parameter in an environment surrounding the sensor, wirelessly transmitting data regarding the level of the parameter to another device, and converting a wireless signal to a current and powering the sensors with the current. The sensor may measure capacitance data and transmit the data to a computer to be converted into temperature readings. The sensor may provide temperature readings from multiple locations within a container into which the sensor is placed.
