Light Sensor
A surface-mount phototransistor, at RZ1, provides light sensitive, variable input for user appli-
cations. Current flow within the phototransistor is inversely proportional to light intensity inci-
dent on the surface of the device. A rail-to-rail OP amp at U5 boosts the photocell output to
useable levels.

Thermal Sensor
An NTC thermistor is provided for thermal sensing applications. The thermistor has an ambi-
ent resistance of 10K ohms. Device resistance falls with increasing temperature. The B pa-
rameter for this device equals 3900

External Drive Piezo Buzzer
A buzzer is provided for use applications requiring audible output. The buzzer is externally
driven with a center frequency (f 0 ) of 2.3 kHz. The buzzer is capable of producing output fre-
quencies ranging from 500 Hz to 5 kHz. The buzzer is connected to a timer channel on the
target MCU allowing frequency modulation.
