Analog Input Controller
The unit to the left was designed as a low power handheld controller designed to read analog 0-5 volt inputs.  This unit uses a microchip PIC16F873 microcontroller with a 10 bit A/D converter.  From this handheld unit, the user has the ability to calibrate the sensor input and select from a number of sensor input ranges.  Software programmed into the microcontroller controlled the display, user interface, and math functions to convert the raw analog input into meaningful data.

RFID Controller
The RFID controller (left) is used to generate a RF signal that is read by a RFID Tag.  If the tag contains the correct sequence, the software triggers a high side driver that operates a solenoid.  This particular controller is capable of controller up to 2 solenoids or other control device.  It uses a microchip microcontroller and an advanced  analog filter and has battery management functions that inform the user when the battery is getting low.

Motor Control
The Motor controller uses a digital speed sensor to control the speed of a DC electric motor.  Control is via a PWM signal generated by the microcontroller.  The controller is battery power and contains a built in battery smart battery charger.  It also accepts a keypad and has a 2 x 16 character LCD display with an advanced software interface which allows the user to calibrate motor speed and set timing sequences.
