Stensat Sensors
Temperature
Will be measured with a Telcom Precision TC02 temperature to voltage converter that is connected to one of the PIC16C73A A/D pins.
Current
Bus current will be measured with a Maxim MAX4172 Precision High-side Current Sense Amplifier connected to another A/D pin.
Voltage
Bus voltage will be measured by comparing the output of a 2.5 volt Linear Technology LT1004 Micropower Voltage Reference that will be connected to another A/D pin.
RSSI
The receiver RSSI output of the Motorola MC13136 is input to another A/D pin.
Sun Sensors
Stensat has three phototransistors connected to three of the PIC16C73 digital pins. The sun sensors are located on the bottom panel, the left side and top side.
