Kit Operation
averaging mode so that ADC count reflects the DC content of rectifier output. The ADC output count
is compared against the threshold value to detect the presence of the metal disk. The threshold
value is selected such that it is less than the peak noise observed on the ADC count to avoid false
triggers.

Interfacing with a Humidity Sensor
Humidity can be measured by measuring the capacitance of a capacitive humidity sensor. A
Cypress CapSense Component is used to measure the capacitance of the humidity sensor. The
CapSense Component provides the best-in-class signal-to-noise ratio (SNR) (>5:1) for sensors with
capacitance up to 200 pF. It also provides high-performance sensing across several varying envi-
ronmental factors such as temperature and humidity.
