€6-12 EUR / hour

am looking to build a compression tester for mazda wankel rotary engine. This will involve a 0-10 BAR pressure sensor outputting 0.5-5Volts into an analog input. This signal is to be fed into an arduino mega. The rotary engine has 3 seperate compression cycles (1 per rotation) On a single "chamber". RPM will need to be determined by counting the time between peak pressure values. The peak value will then be required for each of the 3 rotor faces. Program should be as follows: 1) wait for minimum analog value from sensor to be reached (200) The engine will now be cranked. 2) capture data from sensor over a 5 second period 3) stop capture and analyse the results ata s high a sample rate as possible 4) send results over a serial connection The analysis of the data needs to record the engine RPM based on the "peak pulses" (this will be between 100 and 350 RPM) these pulses form a repeating signal with 3 unique values eg 1-2-3, 1-2-3... with 1 pulse for every 1 rpm The code should allow for detection of 1 or 2 of the pulses to be abnormally low (as low as 150 analog reading. Sample graphs can be supplied if required. Please see attached file for example of signal waveform
