Horsepower Monitor
The Horsepower Monitor measures the torque in an automobile’s
driveshaft and provides an output to a vehicle data recording
system or a portable computer via an RS-232 interface. The received
data then can be combined with rpm measurements from the data
recording system to calculate horsepower. The system consists
of the sensor unit, which attaches to the driveshaft, and the
receiver unit, which provides the serial output signal. Based
on a PIC18F252 microcontroller, the sensor unit is battery powered
and communicates with the receiver via a 433-MHz RF data link.
