Sensor Make and Model

ATMEL MEGA328P 10-bit ADC

How it works

The TSLPB uses one of the analog input channels of its Arduino Pro Mini processor to monitor the voltage (Vcc). When you call readAnalogSensor(Voltage), the TSLPB Library sets the "mux" pins so that the analog input channel is connected to the Vcc rail. The voltage is then read with the onboard Analog to Digital Converter (ADC).
