PLMEX2_RPM_2.0.a.ino: For Module 01M30V0 Basic + adjustment of air.
Target:
The purpose of this software is to display the following data on the computer via the Arduino IDE:
- 2 x Oxygen percentage.
- 2 x Lambda
- 2 x AFR
- 1 x Battery voltage
- 3 x Analogue input voltage. (0-5V)
- Status
- ...
An adjustment to the oxygen measurement can be made to improve measurement accuracy using commands ‘1’, ‘2’, ‘4’ and ‘5’.
Commands that can be sent from Serial Monitor to the Arduino board.
- "1" Adjust lambda 1.
- "2" Removes the adjustment of the lambda probe 1.
- "4" Adjust lambda 2.
- "5" Removes the adjustment of the lambda probe 2.
Hardware required to use this software:
- Arduino board, MEGA, UNO R3, UNO R4, or UNO R4 Wifi or others.
- 1x Lambda module "Controlduino 01M30V00" and wires.
- 2xWideband lambda probe.
- Power supply (V=12v, I>=6A), It is advisable to use a car battery.
Compatible with arduino boards
- Compatibilities with 5V arduino boards.
- Arduino UNO R3.(Bus SPI)
- Arduino UNO R4 mínima.(Bus SPI)
- Arduino UNO R4 WIFI.(Bus SPI)
