An Arduino board coupled to this shield allows to measure the percentage of oxygen contained in the smoke or air, calculate the lambda and AFR( air-fuel ratio of combustion).
- Lambda probe interface BOSCH IC CJ125
- Compatibility with wideband lambda probe BOSCH lsu 4.9
- Compatibilities with arduino boards
- Arduino UNO.(stackable)
- Arduino UNO WIFI.(stackable)
- Arduino MEGA.(stackable, need 3 external wires)
Software available for arduino:
- PLSE_1.0.ino: Basic operation to get started. Sends serial data to the arduino IDE.
- PLSE_2.0.ino: Finite state machine controlled wideband lambda probe operating phases. Sends serial data to the arduino IDE
- PLSE_3.0.ino: (HM10 bluetooth module required). Operation controlled by the Smartphone application, communicating via Bluetooth. This application allows you to turn on and off the heating of the wideband lambda sensor and display the data on the smartphone screen.
- PLSE_4.0.ino: Phases of operation of the broadband lambda probe controlled by finite state machine. Sends data to the 1602 LCD display via I2C.
Smartphone App(HM10 bluetooth module required).
Switches the lambda sensor, displays battery voltage, oxygen percentage, lambda and AFR (air-fuel ratio) for different fuels on the smartphone screen. Is available for the following smartphone platforms:
- IOS(not currently available, available soon)
- Lambda Shield Controduino 01S00V00.
- Wideband lambda probe connection cable (connector 1813139-1) with Shield (Connector 5557).
- Lambda probe, Bosch LSU4.9 or compatible.
- Power Supply(only one required).
- 12V battery and cable with Jack plug.
- 12V AC/DC adapter.
- HM10 Bluetooth low energy module. (Only necessary for use with the smartphone application).
- Arduino board with USB cable.
